1 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the private message sending in the Irssi SILC client,
4 added local command KEY to the Irssi SILC client.
6 Added key management and key agreement message formats to the
7 irssi/src/fe-common/silc/module-formats.[ch].
9 Added USERS (alias WHO) printing, server/router operator
10 indication and LIST command printing to the module formats.
12 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
14 * Fixed channel joining notify handling, cumode notify handling
15 from Irssi SILC client.
17 * Added SILC specific module-formats to the Irssi SILC client so
18 that SILC specific message hilighting, colors etc is possible.
19 Affected file irssi/src/fe-common/silc/module-formats.[ch].
21 Added channel mode, channel user mode, actions, notices,
22 whois and whowas printing to the the module-formats.c.
24 * Fixed a bug in channel deletion in the server. The channel
25 is not left to the cache even if the channel founder auth mode
26 is set when there are no users anymore on the channel. Affected
29 * The silc_net_localhost now resolves the entire hostname including
30 the domain name. Affected file lib/silcutil/silcnet.c.
32 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
34 * Changed the ask_passphrase client operation to be ascynchronous.
35 It has now a completion callback and a context that the
36 application must call after it has got the passphrase from
37 the user. Affected files lib/silcclient/silcapi.h,
38 lib/silcclient/protocol.c, lib/silcclient/command.c and
41 Added SilcAskPassphrase callback that the application calls
42 to deliver the passphrase to the library.
44 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
45 The public key verification and especially a certificate
46 verification is asynchronous procedure.
48 Added new SILC_SKE_STATUS_PENDING status to indicate the
49 request is pending and a callback will be called to finalize
52 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
53 indicate that remote end did not send its public key (or
54 certificate), even though we require it. Added check for this
55 condition in the SKE. This was a security bug, now fixed.
57 Defined new SilcSKEVerifyCbCompletion callback that is called
58 when the verification process is completed.
60 The affected files lib/silcske/silcske_status.h and
61 lib/silcske/silcske.[ch].
63 * Changed the verify_public_key client operation to be async
64 as well. Defined SilcVerifyPublicKey callback that is used to
65 indicate the success of the public key verification process.
67 Changed the server and client to use the new async client
70 * Changed the Irssi SILC client's internal scheduler to be called
71 twice as many times as it used to be. As a result the client
72 should be a bit faster now. Affected file is
73 irssi/src/silc/core/silc-core.c.
75 * Added support to Irssi SILC client of asynchronous public key
76 verification and passphrase inquiry. Affected file is
77 irssi/src/silc/core/silc-core.c.
79 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
81 * Do not say "You have left channel %s" in client library.
82 Moved it to the application. Affected files are
83 lib/silcclient/command.c and silc/client_ops.c.
85 * Fixed silc_client_get_clients. Command context was not
86 duplicated and was freed memory in the callback. Affected
87 file lib/silcclient/idlist.c.
89 * Do not say "you are now talking..." on JOIN command in the
90 client library. The appliation must handle it.
92 * Do not say ".. changed topic to" in command reply in the
93 client libary. The application must handle it.
95 * Fixed TOPIC command sending in the client library.
97 * Fixed a memory leak in silc_client_command_free in the file
98 lib/silcclient/command.c.
100 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
102 * Imported a modified version of Irssi client to the source tree.
103 The Irssi will be used to create a new client called
104 Irssi SILC. Imported to irssi/.
106 Added silc_core_init_finish function to the Irssi. Affected
107 file irssi/configure.in.
109 A lot changes in the Makefile.ams around the irssi tree.
111 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Do not rehash if the new size is same as the old size of the
114 hash table, in the silc_hash_table_rehash*. The affected file
115 lib/silcutil/silchashtable.c.
117 * Replaced hash_table_del_by_context calls from the server
118 (when channel->user_list and client->channels) to the
119 hash_table_del as it is sufficient and faster.
121 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Added silc_hash_table_list, silc_hash_table_get and the
124 SilcHashTableList structure to provide an alternative way to
125 traverse the hash table. The affected files are
126 lib/silcutil/silchashtable.[ch].
128 * Changed the server's idlist routines to use the hash table
129 routines to optimize the code.
131 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Replaced the client entry's `channel' list and channel entry's
134 `user_list' list to hash tables for optimized lookup. Changed
135 the code to use the hash table interface around the code.
136 Affected file lib/silcd/idlist.[ch].
138 * Added `auto_rehash' boolean argument to the function
139 silc_hash_table_alloc to indicate whether the hash table should
140 auto-rehash when it thinks is appropriate time. It will
141 increase the hash table size if the there is twice as much
142 entries in the table than the size of the table, and will
143 decrease the size if there are twice as less entries than
144 the size of the table.
146 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
148 * Fixed silc_xxx_get_supported to not crash at some circumstances.
150 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
152 * silc_idcache_purge_by_context deletes the entry now by context
153 as it is supposed to do. Affected file lib/silccore/idcache.c.
155 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
156 client is not anymore valid (WHOWAS givens the info) and not
157 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
159 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
161 * Removed the `data' and `data_len' arguments from the ID Cache
162 interfaces and added `name' argument. ID Cache does not handle
163 anymore the binary data only a names associated with given ID.
165 * When hashing a Client ID with silc_hash_id the entire ID is
166 not hashed anymore, instead only the hash of the Client ID is
167 hashed. This way we can access the Client ID from the cache
168 with Client ID but with the hash of the ID (which is a hash of
169 the nickname) as well without any difference in performance.
171 Added also silc_idcache_find_by_id_one_ext to do one on one
172 searching when we have the actual ID. Added also function
173 silc_hash_client_id_compare. The affected files are
174 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
176 * When hashing the name associated with a ID it is always done
177 in lowercase. This way we can access the cache without worrying
178 about case-sensitivity, even though, for example nicknames are
181 * Fixed a bug in server with channel message sending. It put
182 wrong ID type as destination ID. The affected file
185 * silc_idcache_del_by_context now deletes from all hash tables
186 by context. Affected file lib/silccore/idcache.c.
188 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
190 * Changed the client library to use the new ID Cache interface.
191 Changes around the source tree.
193 * Added silc_hash_table_rehash_ext to rehash with specific
194 hash function. Affected file lib/silcutil/silchashtable.[ch].
196 * Added silc_hash_string_compare to compare two strings in the
197 hash table. Affected file lib/silcutil/silcutil.[ch].
199 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Added new function silc_idcache_del_by_context into the
202 lib/silccore/idcache.[ch].
204 * Changed the server's ID list routines to use the new ID Cache
205 interface. Changes around the source tree.
207 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Added silc_hash_table_del[_by_context]_ext functions in to the
210 lib/silcutil/silchashtable.[ch].
212 Removed silc_hash_table_find_all* routines and added new
213 silc_hash_table_find_foreach to replace them.
215 Added silc_hash_table_replace_ext function as extended
216 replacing function. Separated the simple hash table interface
217 from the extended hash table interface in the file
218 lib/silcutil/silchashtable.h.
220 * Fixed minor bugs and changed it to use some of the new
221 hash table functions in lib/silccore/idcache.c
223 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Added new function silc_hash_table_find_all to return all keys
226 in the hash table by the specified key. As the hash table is
227 collision resistant it also makes it possible to have several
228 duplicate keys in the hash table. This function may be used to
229 find all of the keys from the hash.
231 Added user_context arguments to the SilcHashFunction,
232 SilcHashCompare and SilcHashDestructor to deliver user specified
235 Added new fuctions silc_hash_table_find[_all]_ext to do
236 extended lookup with specified hash and compare functions and
237 specified user contexts.
239 Added new function silc_hash_table_add_ext to add the key
240 with specified hash function and user context.
242 Added new function silc_hash_table_foreach to traverse all
243 entrys in the hash table. Added SilcHashForeach callback
246 Added new function silc_hash_table_del_by_context to delete
247 the entry only if the context associated with the key matches.
249 Affected files are lib/silcutil/silchashtable.[ch].
251 * Removed silc_hash_[server/client/channel]_id and added just
252 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
253 silc_hash_id_compare to compare two ID's using as the hash table
254 comparison function. Added also silc_hash_data to hash
255 binary data and silc_hash_data_compare to compare it.
257 * Removed silc_idlist_find_client_by_hash as it is not needed
258 anymore. Affected file silcd/idlist.[ch].
260 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
261 to use internally the SilcHashTable. The new ID Cache is a lot
262 faster than the old one. Some of the ID Cache interface was also
263 rewritten and obsolete and stupid functions were removed.
265 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * Added entry_count field to the SilcHashTable to keep the number
268 of the entries in the table. Implemented the function
269 silc_hash_table_rehash. Added new function
270 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
272 Fixed a minor bug in silc_hash_table_free.
274 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
275 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
276 into the lib/silcutil/silcutil.[ch].
278 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Implemented a collision resistant hash table into the
281 lib/silcutil/silchashtable[ch]. See the header and the source
282 for the SilcHashTable API.
284 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Merged dotconf version 1.0.2 into lib/dotconf.
288 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
290 * Do not compile anything in lib/silcsim/* if the SIM support
291 is not enabled. The tree should now compile without problems
294 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
296 * Compiled the SILC under cygwin. Compiled and tested briefly
297 without problems. More tests needed. The SIMs didn't compile
300 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
302 * Fixed possible crash in silc_get_username in the
303 lib/silcutil/silcutil.c.
305 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
307 * Fixed a va_arg in silc/client_ops.c.
309 * Oops, RC5 routines were named AES and caused some problems
310 when not using SIM's. Affected file lib/silccrypt/rc5.c.
312 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Added new SilcIDIP structure into the lib/silccore/id.h and
315 replaced the old `ip' fields from all SILC ID's to that type.
316 This is a step towards IPv6 support.
318 The silc_id_get_len takes now the ID as an extra argument.
319 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
320 both IPv4 and IPv6 based ID's.
322 The affected files are lib/silccore/id.[ch] and other files
323 around the tree using these routines.
325 * Removed the ID length arguments in server from various
326 silc_server_send_notify_* routines -> they are not needed
329 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Fixed memory leak in silc_encode_pem_file in the file
332 lib/silcutil/silcutil.c.
334 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Check minor version as well in the SKE. Affected files are
337 silcd/protocol.c and lib/silcclient/protocol.c.
339 * Added --identifier option to the server so that an identifier
340 can be when creating the public key for the server. Affected
341 file is silcd/silcd.c.
343 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
344 lib/silccrypt/silcpkcs.c.
346 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Register default ciphers and stuff when using -C option with
349 the server. Affected file sildc/silcd.c.
351 * Put back the servers public key filename format, it is better
352 than the new one. For now, the client keys are saved with the
353 new filename format. The affected file silc/client_ops.c.
355 * Implemented the Cipher API for the rest of the ciphers that
356 did not implement it or implemented it the wrong way.
358 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
360 * Register default ciphers and stuff when using the -S option
361 in the client. Affected file silc/silc.c. Same also when
362 creating new key pair with -C option.
364 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Fixed the silc_verify_public_key client operation function to
367 save the public keys differently. The fingerprint is now
368 used as filename and not the hostname. This way also the
369 client keys are saved uniquely and not with hostnames. The
370 affected file is silc/client_ops.c.
372 * Trimmed the silc_hash_fingerprint function to remove extra
373 whitespaces from the end of the fingerprint. The affected
374 file is lib/silccrypt/silchash.c.
378 * Added silc_cipher_register_default function to register all
379 default ciphers. It can be used when configuration files
380 does not exist and the application does not want any specific
381 ciphers in any specific order.
383 The SilcDList is now used as silc_cipher_list dynamically
384 allocated cipher list. Removed the static list all together
385 and now all ciphers must be allocated to the dynamic list.
386 The silc_cipher_alloc routine was changed to check only the
389 All silc_cipher_* routines that used to return int returns
392 The affected files lib/silccrypt/silccrypt.[ch].
394 * The same thing was done to silc_hash_* as for silc_cipher_*
395 routines. Affected files lib/silccrypt/silchash.[ch].
397 * The same thing was done to silc_pkcs_* as for silc_cipher_*
398 routines. Affected files lib/silccrypt/silcpkcs.[ch].
399 Added also silc_pkcs_[un]register[_default] functions.
400 Removed the data_context from the PKCS API.
402 * Added silc_hmac_register_default function to register default
403 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
404 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
405 to unregister all hmacs at once.
407 * Register the default ciphers, hash functions, PKCSs and HMACs
408 if client's configuration file does not exist. The affected
411 * The client did not load the hash functions from the SIM
412 modules at all. Added support for this. Affected file is
415 * When decoding public key with silc_pkcs_public_key_decode, check
416 the supported algorithm only if PKCS are registered. Affected
417 file lib/silccrypt/silcpkcs.c. The same was done with the
418 silc_pkcs_private_key_decode.
420 * Fixed the SILC List routines to keep the list always in order.
421 It used to change the list's order when traversing the list but
422 not it preserves the order. Affected file lib/trq/silclist.h.
424 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
426 * Added the client library to use the SilcSocketConnection's
427 reference counter (by silc_socket_dup) to prevent the bug that
428 the socket object may be freed underneath async operation.
430 * The name resolv library checking fixes in the configure.in.pre.
433 * Created new version of the protocol drafts for future
434 development. The -03 drafts are the ones that will be changed
435 in the trunk now and the -02 will remain as they are.
437 * Send list of CUMODE notifys to the router when announcing
438 the channel users to the router. Affected file silcd/server.c.
439 If the router receiving channel founder CUMODE for a channel
440 that already has channel founder it will send CUMODE notify
441 to the sender to remove the channel founder rights from the
442 announced client. Affected file silcd/packet_receive.c.
444 * The CUMODE notify may now use Server ID as well as the entity
445 who changes the mode. Updated protocool specs.
447 * Updated INSTALL and README files.
449 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
451 * New web pages in the http://silc.pspt.fi. The pages was
456 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
458 * Implemented the [DenyConnectin] config section in the server.
459 Added silc_server_config_denied_conn to check whether incoming
460 connection is denied. Affected file silcd/serverconfig.[ch].
462 * Do not check the ports when checking the incoming configuration
463 data if the port is 0, meaning any. Affected file is
464 silcd/serverconfig.c.
466 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
468 * Fixed buffer overflow in silc_string_compare in the file
469 lib/silcutil/silcutil.c.
471 * Fixed double free in silc_server_command_leave in the file
474 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Fixed the version checking in the server. Affected file is
479 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Fixed the configuration data fetching when accepting new
482 connections in the server. Affected file silcd/server.c.
484 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Added `sender_entry' argument to the function
487 silc_server_packet_relay_to_channel so that we can check
488 whether some destination actually belongs to the same route
489 the sender belongs (ie, we must not resend the packet to the
490 sender). Affected file silcd/packet_send.[ch].
492 * Added `servername' field to the SilcClientEntry in the server
493 to hold the name of the server where client is from. Affected
494 file is silcd/idlist.h.
496 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
498 * Moved the channel message encrypting in the router betwen
499 router connections from silc_server_channel_message to the
500 silc_server_packet_relay_to_channel since we want to check
501 whether we have anybody channel before encrypting anything.
502 Affected files silcd/packet_[receive/send].c.
504 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
506 * Fixed the [AdminConnection] server config section to support
507 multiple entries. Affected file silcd/serverconfig.c.
509 * Added support into the server to check the validity of the
510 incoming connection before executing any KE or authentication
513 * The connection configuration is now saved to the KE and
514 connection auth protocol contexts and not fetched anymore in
515 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
517 * The local hosts listenning address and port is also resolved
518 now when starting the server. We want to have the socket object
519 to include the real address and port for the listener. Added
520 new function silc_net_check_local_by_sock into the files
521 lib/silcutil/silcnet.[ch].
523 * Fixed a broadcast bug in server -> do not broadcast if we
526 * Fixed a routing bug. Do not route broadcast packets ever.
527 Broadcast packets must be processed always and not routed since
528 they may be destined to some other host than yourself and thus
529 would get routed without no good reason. Affected file is
532 * Added function silc_server_config_is_primary_route to check
533 whether primary router connection has been configured (a router
534 configuration that we are initiating). If there is not, we
535 will assume that there is only two routers in the SILC network
536 and we will use the incoming router connection as our primary
537 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
539 * Changed the order of the broadcasting. Broadcast _after_ the
540 packet has been processed not before. Affected file is
543 * Fixed a [ClientConnection] parsing bug. The port was never
544 parsed correctly thus resulting to port 0. Affected file
545 silcd/serverconfig.c.
547 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
548 argument and did not set the broadcast packet flag. Affected
549 file silcd/packet_send.c. Fixed same bug in the function
550 silc_server_send_notify as well.
552 * If we receive NEW_ID packet for our own ID in the server, ignore
555 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Removed the nickname from the Private Message Payload.
560 Updated the code and the protocol specs.
562 * Updated protocol specs for submitting to the IETF.
564 * Tweaked the Random Number Generator a bit. Affected file
565 lib/silccrypt/silcrng.c. Exported a new function
566 silc_rng_[global]_add_noise which can be used to add more
569 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * Do not parse packets with different timeout when protocol
572 is active -> may cause problem with rekey. Affected file
575 * When server receives signoff notify it must not create
576 new channel key if the client is on any channels since the
577 sender of the signoff notify will create it.
579 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
581 * Added printing of error messages during SKE protocol from the
582 failure packet sent by server during SKE. Affected file
585 * Removed the client's failure_callback handling with timeout
586 and handle it immediately when received.
588 * The SKE library returned wrong type in SUCCESS and FAILURE
589 packets. They must be 32 bit MSB not 16 bit MSB.
591 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
593 * Ok, rewrote the logic of the re-key and now it seems to work.
594 I tested it on high traffic with frequent re-keys without
595 problems. Added hmac_receive (and renamed hmac to hmac_send)
596 in SilcClientConnection in lib/silcclient/client.h and
597 in SilcIDListData in silcd/idlist.h. Also, removed the
598 SilcPacketParserContext's cipher and hmac fields as they are
599 not needed anymore and actually caused some problems when
600 the ciphers and hmac's changed underneath the packet parser.
602 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * If re-key protocol is active then process the incoming packets
605 synchronously since we must assure that icoming packets encrypted
606 with the old key is processed before the new keys is set to
607 use. This is true other packets than for REKEY packets.
608 Affected file silcd/server.c. The same was done to client library
609 as well, affected file lib/silcclient/client.c.
611 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
613 * Fixed bug in client and server to accept the force send if
614 the packet is send from silc_[server/client]_packet_process
615 function. Otherwise the packets are never delivered, oops.
617 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Disable force sending of packets when REKEY protocol is active.
620 We must assure that no packet is sent directly when rekey is
621 performed. All packets must be sent through packet queue.
622 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
623 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
624 function is silc_[server/client]_packet_send_real to check
627 * Replaced the SIM paths from example config files to
628 /usr/local/modules. Also, make install creates now
629 /usr/local/silc/logs directory to hold all the SILC server
632 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Made the configure.in.pre work on Solaris. Patch by salo.
636 * Made all ciphers compatible with non-x86 machines. Defined
637 CBC mode macros into lib/silccrypt/ciphers_def.h.
639 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Fixed the make install.
643 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
645 * When MAC computation fails the silc_packet_decrypt returned 0
646 even though it was supposed to return -1. Fixed this. The
647 affected file is lib/silccore/silcpacket.c.
649 * Do not replace the config files in /etc/silc (in make install)
650 if they already exist. Affected file ./Makefile.am.
652 * Do not send re-key packets immediately but through packet queue.
653 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
655 * Changed silc_net_check_host_by_sock to return FALSE if the
656 IP/DNS could not be resolved. Though, it returns the IP address
657 now even if it could not resolve it (but returns also FALSE).
658 Affected file lib/silcutil/silcnet.[ch].
660 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
662 * Added silc_pkcs_decode_identifier to decode the public key's
663 identifier. Affected file lib/silccrypt/silpkcs.[ch].
664 Added also silc_pkcs_free_identifier. Added also new context
665 SilcPublicKeyIdentifier.
667 * Added -S option to the silc client. It is used to dump the
668 contents of the specified public key file.
670 * Changed the PKCS api to return the public key length when
671 setting the public key.
673 * Fixed a fatal bug in the public and private key file loading.
674 Affected file lib/silccrypt/silcpkcs.c.
676 * Execute the packet parsing for client with zero (0) timeout
677 if the protocol is active. Affected file silcd/server.c.
679 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Made the key generation options to the silcd program. Added
682 -C option, equivalent to client's option.
684 * Added new [ServerKeys] config section to the server. It
685 configures the server's public and private key.
687 * Defined generic Public Key Payload into the protocol
688 specification to send specific type of public keys and
691 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
692 public key or certificate.
694 * Implemented the GETKEY command to the server and to the
695 client library and on user interface.
697 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Made preliminary `make install' work.
701 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Added SilcServerRekey context into silcd/idlist.h.
705 * Added the PFS support as defined in the specification to the
706 SKE protocol. Affected files lib/silcske/*.c.
708 * Added `ske_group' field to the SilcServerRekey context to hold
709 the number of the SKE group that is used with PFS in re-key.
710 Affected file silcd/idlist.h.
712 * Added PFS re-key support to the server. Affected file is
715 * Added silc_protocol_cancel to cancel execution of the next
716 state of the protocol. Affected file is
717 lib/silccore/silcprotocol.[ch].
719 * Added the re-key support with and without PFS to the client
720 library. Re-key is performed once in an hour, by default.
722 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
723 Added silc_client_rekey_callback and silc_client_rekey_final.
724 Affected files are lib/silcclient/protocol.[ch] and
725 lib/silcclient/client.[ch].
727 * Removed the `hmac_key' and `hmac_key_len' fields from the
728 SilcClientConnection structure; not needed. Affected file is
729 lib/silcclient/client.h.
733 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
735 * Do not ask whether user wants to use the negotiated private key
736 for private messages, just use it. Affected file is
737 silc/local_command.c.
739 * Added `send_enc_key' and `enc_key_len' fields to the
740 SilcIDListData structure since they are needed in the re-key
741 phase. Affected file is silcd/idlist.[ch].
743 * Implemented the simple re-key protocol into the server.
744 Affected files silcd/server.c and silcd/protocol.[ch]. The
745 re-key will be performed once in an hour, by default.
747 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
748 Added silc_server_rekey, silc_server_rekey_callback and
749 silc_server_rekey_final.
751 * Removed Tunneled flag from the protocol. Updated the code
752 and the specifications.
754 * Adde `pfs' field to the SilcIDListData to indicate whether
755 the PFS is to be performed in the re-key. Affected file is
758 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
761 int64 of at least the xintXX size. If void * is less that 4
762 bytes uint32 * will be used. Defined bool as boolean.
764 * Changed _ALL_ unsigned long and unsigned int to uint32,
765 unsgined short to uint16 in the source tree.
767 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
768 not handle clients that has entry->data.registered == FALSE.
769 They are not in the network anymore. Affected file is
772 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
774 * Implemented the sending of the SERVER_SIGNOFF notify in the
775 server. Affected file is silcd/server.c.
777 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
778 Added also silc_notify_payload_encode_args into the
779 lib/silccore/silcnotify.[ch].
781 * Implemented ther SERVER_SIGNOFF notify handling in the server.
782 Affected file silcd/packet_receive.c.
784 * Implemented the SERVER_SIGNOFF notify handling in the client
785 library. Affected file lib/silcclient/client_notify.c. Also,
786 implemnted the printing of the SERVER_SIGNOFF info to the
787 application. Affected file silc/client_ops.c.
789 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
790 if the deleting was successful. Affected file silcd/idlist.[ch].
792 * Added support for public key authentication in the connection
793 authentication protocol in the client library. Affected file
794 lib/silcclient/protocol.c.
796 * Changed the server's silc_idlist_get_clients_by_* interface
797 to support already allocated array so that new entries may be
798 added to pre-allocated array. Affected file silcd/idlist.[ch].
799 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
802 * All command reply functions in the server now calls the
803 pending command callback even if error occured. This way the
804 error will be delivered to the client as well. Affected files
805 silcd/command.c and silcd/command_reply.c.
807 * Fixed INFO command to return local server's info if no server
808 was provided. Affected file lib/silcclient/command.c.
810 * Removed RESTART command for good. Updated the code and the
813 * Rewrote parts of the task system. It is a bit simpler now.
814 Removed unsued task priorities. The affected files are
815 lib/silcutil/silctask.[ch].
817 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Moved the USERS printing from the library to the application.
820 Affected files lib/silcclient/command.c and silc/client_ops.c.
822 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
826 * Added channel key re-key support. The re-key is perfomed
827 only by the router and is done once in an hour. Added `rekey'
828 field to the SilcChannelEntry in the server. Affected files
829 silcd/server.c and silcd/idlist.h.
831 * Added silc_task_unregister_by_context into the file
832 lib/silcutil/silctask.[ch].
834 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added SILC_UMODE_GONE mode to indicate when the client is not
837 present in the SILC network. Added also support to the local
838 command AWAY that will set this mode. Added support of showing
839 "xxx is gone" in WHOIS command. The USERS command shows the
842 * Fixed setting server and router operator privileges in the
843 server's UMODE command. Affected file silcd/command.c.
845 * Merged the SKE KE1 and KE2 payloads into one payload. The
846 new KE payload is equivalent to the old KE2 payload.
848 Cleaned up the SKE Start Payload parsing. It now uses the
849 simple buffer unformatting to do the parsing. A lot faster
852 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
853 to the SKE that is used to indicate whether both of the SKE
854 parties should perform authentication. By default only the
855 responder performs authentication. By setting this flag also
856 the initiator must do authentication. By default it is unset
857 since in normal SKE case, client to server connection, only
858 the responder should do authentication. When doing SKE between
859 two clients both should perform authentication. Updated the
860 code and the protocol specs.
862 * A little fix to IDENTIFY command in the server. Search the
863 client first by hash not nickname. Affected file is
866 * Fixed the silc_client_close_connection to support closing
867 the client to client connections wihtout deleting too much
868 data. Affected file lib/silcclient/client.c.
870 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
871 are received if protocol used to be active but is not anymore
872 the application would crash due to NULL pointer dereference.
873 Affected files silcd/server.c and lib/silcclient/client.c.
875 * Added `hash' field to the SilcClientConnection to include
876 the hash function negotiated in the SKE protocol.
878 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
879 to set the channel founder authentication data. A client can
880 claim the founder rights later by providing the authentication
881 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
882 This way the channel founder can regain the channel founder
883 privileges even it is left the channel. This works only on
884 local server and the client must be connected to the same
885 server to be able to regain the founder rights. Updated the
886 protocol specs accordingly.
888 Added support to the CMODE command in the client to set the
889 founder auth data. Read the README to see how to set it.
891 Added support to the CUMODE command to claim the founder
892 rights. Read the README to see how to do it.
894 Added support for the founder authentication to the Channel
895 Entry in the server. Affected file silcd/idlist.h.
897 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
898 server's CMODE command. Affected file silcd/command.c.
900 * Added the following new functions into lib/silccore/silcauth.[ch]:
901 silc_auth_get_method and silc_auth_get_data.
903 * The server now saves the remote hosts public key to the
904 SilcIDListData pointer. Affected file silcd/protocol.c.
906 * The normal server now does not remove the channel entry from
907 the cache if the founder authentication data is set. It used
908 to remove it if the founder was the last one on the channel on
909 the server and left the channel. The auth data is saved and
910 if the channel is re-joined later the old entry is used with
911 the old auth data. Affected files silcd/command_reply.c and
914 * Removed the `pkcs' field from the SilcIDListData structure
915 in the server; it is not used. Affected file silcd/idlist.h.
917 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Fixed packet processing on slow links. Partial packets were
920 never re-processed because the incoming data buffer was cleared
921 by the application. Application must not directly clear the
922 sock->inbuf, the packet processing routines handle it. Fixed
923 this in client library and in server.
925 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
927 * Fixed the WHOIS and IDENTIFY send reply function to really
928 check whether to send list or just one entry. Affected file
931 * Cleaned up the LEAVE command's channel key distribution. The
932 affected file silcd/command.c.
934 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
935 can enforce the channel mode as well. In that case the ID
936 includes the ID of the server. The code now enforces the
937 mode change if the router have different mode than the server.
939 * The notify client operation with CMODE_CHANGE notify can now
940 return NULL client_entry pointer if the CMODE was not changed
941 by client. Application must check for this.
943 * Added <Server ID> argument to INFO command to support server
944 info fetching by Server ID.
946 * Added silc_server_announce_get_channel_users to get assembled
947 packets of channel users of the specified channel. Affected
948 file silcd/server.[ch].
950 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
951 was freed underneath the ID Cache.
953 * Re-announce clients when the server received CHANNEL_CHANGE
954 notify from the router. Affected file silcd/packet_send.c.
956 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
959 crashed since it did not handle the fact that there is no cipher
960 called "3" and didn't check the error condition. Now fixed.
962 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
963 flag. It can be used to send message requests.
965 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * Implemented the RESTART command in the client.
969 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
970 notice type messages. Added notice printing to the user
973 * The channel keys are not re-generated if the channel's mode
974 is PRIVKEY, ie private key on the channel exists. Affected
975 files silcd/server.c and silcd/command.c.
977 * Fixed a little bug in channel message delivery when channel
978 private keys are set in the server. Affected file is
981 * Changed the setting on channel->on_channel = TRUE from the
982 silc_client_save_channel_key to the JOIN command reply. The
983 key payload is not received if the private channel key is set.
984 Affected file lib/silcclient/command_reply.c and the
985 lib/silcclient/client_channel.c.
987 * When the CMODE_CHANGE notify is sent and the channel private
988 key mode is removed the channel key must be re-generated in
989 other cells as well. Added this support for the router in the
990 silcd/packet_receive.c.
992 * Added new local command NOTICE to send notice message on
993 channel. Affected file silc/local_command.[ch].
995 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Added new local command ME to the client. It is used to send
998 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
999 some action. Affected file silc/local_command.[ch].
1001 * Changed channel_message and private_message client operations
1002 to deliver the message flags to the application. Added also
1003 the `flags' arguments to the silc_client_send_channel_message
1004 and silc_client_send_private_message functions. Affected file
1007 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1009 * Redefined the Private Message Payload to support private message
1010 keys and to support the new private message flags. Updated
1011 the protocol specs. Flags makes it possible to have for example
1012 CTCP style messages.
1014 * Added new type SilcPrivateMessagePayload and defined an API
1015 for it in the lib/silcclient/silcprivate.[ch].
1017 * Tested private message private keys successfully. Tested the
1018 private message key set, unset and list commands with the new
1021 * Redefined the Channel Message Payload to include the channel
1022 message flags (equal with private message flags) to support
1023 for example CTCP style messages.
1025 * Defined some of the message (for channel and private message)
1026 flags. Updated the protocol specs and added the flags to the
1027 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1029 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1031 * Added SilcKeyAgreementStatus type to the key agreement routines
1032 to indicate the current status and error if one occured.
1033 The status types are defined in the lib/silcclient/silcapi.h.
1035 * Added new local command KEY that is used to set and unset private
1036 keys for channels, set and unset private keys for private messages
1037 with remote clients and to send key agreement requests and
1038 negotiate the key agreement protocol with remote client. The
1039 key agreement is supported only to negotiate private message keys,
1040 it currently cannot be used to negotiate private keys for channels,
1041 as it is not convenient for that purpose.
1043 * Fixed a minor pending callback setting bug in the function
1044 silc_client_get_client_by_id_resolve, now the function works.
1045 Affected file lib/silcclient/idlist.c.
1047 * Added function silc_net_get_local_port to get local bound
1048 port by socket. Added to lib/silcutil/silcnet.[ch].
1050 * Added `sockets' and `sockets_count' fields to the SilcClient
1051 object. They hold the sockets of the listenning sockets in
1052 the client. Listenning sockets may be for example the key
1053 agreement server. Affected file lib/silcclient/client.[ch].
1054 Added functions the silc_client_add_socket and the
1055 silc_client_del_socket. They are exported to the application
1058 * Added ~./silc/clientkeys to support other client's public keys.
1060 * Renamed verify_server_key client operation to verify_public_key
1061 and added one argument to indicate the type of the connection
1062 (server, client etc.).
1064 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * Added silc_server_connection_auth_request to handle the
1067 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1068 silcd/packet_receive.[ch].
1070 * Added silc_server_send_connection_auth_request into the
1071 silcd/packet_send.c to send the connection auth request packet.
1073 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1076 * Fixed the public key authentication in responder side in the
1077 server. The `auth_data' pointer includes the SilcPublicKey
1078 not the path to the public key. Affected file silcd/protocol.c.
1080 * Implemented the public key authentication in the initiator side
1081 in the server. Affected file silcd/protocol.c.
1083 * Removed the [RedirectClient] config section from the server
1084 configuration. Is not needed and I don't want to implement it.
1086 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Cleaned up the CMODE command in the server. It now works
1089 correctly and supports all the modes defined in the protocol.
1090 Affected file is silcd/command.c.
1092 * Added `hmac_name' field to the SilcChannelEntry in the server
1093 to hold the default HMAC of the channel. It can be set when
1094 creating the channel (with JOIN command). Affected files
1097 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1098 type to indicate the change of the current cipher and hmac
1099 on the channel. Client can safely ignore the <cipher> argument
1100 (if it chooses to do so) since the CHANNEL_KEY packet will
1101 force the channel key change anyway. The <hmac> argument is
1102 important since the client is responsible of setting the new
1103 HMAC and the hmac key into use.
1105 * Fixed the CMODE command in the client library as well.
1107 * Tested CMODE command in router environment successfully.
1109 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1111 * Show the version of the remote client (or server) when connecting
1112 to the server. It is logged to the log file. Affected file
1113 is silcd/protocol.c.
1115 * Fixed the KILLED notify handling in the client library. The
1116 client must be removed from all channels when receiving the
1119 Also, do not remove the client entry when giving the KILL
1120 command but when the KILLED notify is received.
1122 * Removed silc_idlist_find_client_by_nickname from the server.
1123 Not needed anymore. Affected files silcd/idlist.[ch].
1125 * Implemented the CHANNEL_CHANGE notify type handling to the
1126 server. Affected file silcd/server.c.

1133 notify between routers.
1135 * Implemented the INVITE command correctly to the server.
1137 * Implemented the INVITE notify type handling in the server.
1139 * Implemented the INVITE command to the client library and on the
1142 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Added function silc_server_get_client_resolve to find the
1145 client entry by ID from all ID lists and then resolve it
1146 (using WHOIS) if it cannot be found. Affected file is
1149 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1151 * Implemented the BAN command to the client library.
1153 * The JOIN command in the server now checks the invite list
1156 * Changed the silc_command_reply_payload_encode_va and the
1157 silc_command_payload_encode_va to support that if argument is
1158 NULL it ignores and checks the next argument. Affected file
1159 lib/silccore/silccommand.c.
1161 * Added silc_server_send_notify_ban to send the BAN notify
1162 type between routers.
1164 * Chaned the silc_notify_payload_encode to support that if
1165 argument is NULL it ignores and checks the next argument.
1166 Affected file lib/silccore/silcnotify.c.
1168 * Tested ban lists in router environment successfully.
1170 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Implemented BAN command to the server, in silcd/command.[ch].
1174 * Removed the BAN and INVITE_LIST modes from the CMODE command
1177 * Added function silc_string_match to regex match two strings.
1178 Affected files lib/silcutil/silcutil.[ch].
1180 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Redefined parts of the SilcChannelEntry in the server to support
1183 the new ban and invite lists.
1185 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1187 * Redefined the INVITE command. The same command can be used to
1188 invite individuals to the channel but also to manage the invite
1189 list of the channel (to add to and remove from the invite list).
1190 Updated the protocol specs.
1192 * Added new command SILC_COMMAND_BAN that can be used to manage
1193 the ban list of the channel. Updated the protocol specs.
1195 * Removed the channel modes: the SILC_CMODE_BAN and the
1196 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1197 in the CMODE command. The equivalent features are now available
1198 using INVITE and BAN commands. Updated the protocol specs.
1200 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1201 in the network about change in the current ban list. The notify
1202 type is not used by the client.
1204 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1205 support the invite lists.
1207 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Added new function silc_string_regexify that converts string
1210 including wildcard characters into regex string that can
1211 be used by the GNU regex library. Added into the file
1212 lib/silcutil/silcutil.[ch].
1214 Added silc_string_regex_combine to combine to regex strings
1215 into one so that they can be used as one regex string by
1216 the GNU regex library. Added into the file
1217 lib/silcutil/silcutil.[ch].
1219 Added silc_string_regex_match to match two strings. It returns
1220 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1222 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1224 * Imported GNU regex to the soruce tree into lib/contrib.
1225 Fixed some compiler warning from the regex.c.
1227 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Fixed MOTD command in the server to work in router environment.
1231 * Fixed the MOTD command in the client library to support
1232 the server argument in the command.
1234 * Added `nickname_len' argument to the silc_idlist_add_client
1235 in the server, as the `nickname' argument may be binary data
1238 * Added silc_idlist_get_channels to return all channels from
1241 * Implemented LIST command to the server. Affected file is
1244 * Implemented the LIST command to the client library and on the
1247 * Added [<user count>] argument to the LIST command reply.
1248 With private channels the user count is not shown.
1250 * Updated TODO and README.
1252 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * The client entry's data.registered must be TRUE even with
1255 global client entry on global client list. The data.registered
1256 is used to check whether the client is anymore in the network,
1257 for example with WHOWAS command so it must be valid.
1259 * Fixed the WHOWAS command in the server. It now actually works
1260 in router environment. Added function into silcd/command_reply.c
1261 silc_server_command_reply_whowas_save.
1263 * Added silc_idlist_purge function to the silcd/idlist.c
1264 to periodically purge the ID Cache.
1266 * Fixed INFO command in the server. It works now in router
1267 environment. Added <server name> argument to the INFO command
1268 reply. Updated the protocol specs.
1270 * Fixed minor bug in silc_idcache_purge to not purge if the
1271 expire value is zero.
1273 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1274 they were buggy because of the WHOWAS information.
1276 * Fixed local command MSG to handle the async resolving of
1277 the remote client properly. It used to fail the first MSG.
1278 Affected file silc/local_command.c.
1280 * Added `data_len' field to SilcIDCache context.
1282 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Update TODO. Todo in commands in the server.
1286 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1288 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1289 used by routers as broadcast packet to inform other routers
1290 about the changed user mode.
1292 Implemented the notify handling in the server. Affected file is
1293 silcd/packet_receive.c. Added the function
1294 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1296 * Added new generic Channel Payload and deprecated the New Channel
1297 Payload. The New Channel Payload is now the generic Channel
1300 * Added new argument `mode' to the silc_server_send_new_channel
1301 as it is required in the Channel Payload now.
1303 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1304 and created a new and real SilChannelPayload to represent the
1305 new generic Channel Payload. Implemented the encode/decode
1306 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1308 * Added silc_server_get_client_channel_list to return the list
1309 of channels the client has joined for WHOIS command reply.
1310 Affected file silcd/server.[ch].
1312 * Implemented the channel list sending in the WHOIS command reply
1313 in server and in the client.
1315 Implemented the channel list displaying on the user interface
1316 as well. Affected file silc/client_ops.c.
1318 * Added silc_channel_payload_parse_list to parse list of Channel
1319 Payloads. It returns SilcDList list of SilcChannelPayloads.
1320 Client for example can use this function to parse the list of
1321 channels it receives in the WHOIS command reply. The caller
1322 must free the list by calling silc_channel_payload_list_free.
1323 Affected files lib/silccore/silcchannel.[ch].
1325 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Added one new argument <user mode> to the WHOIS command reply
1328 to return the mode of the user in SILC. Updated the protocol
1331 Implemented it to the server and client.
1333 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1335 * Fixed the mode printing on the user interface on joining.
1336 Affected file silc/client_ops.c.
1338 * Implemented the UMODE command and user modes in general to the
1339 client library and to the user interface.
1341 * Implemented the UMODE command to the server.
1343 * The server now sends UNKNOWN_COMMAND error status if client sends
1344 unknown command. Affected file silcd/command.c.
1346 * All server commands now handle the command identifier the right
1347 way when sending the command reply to the client. The client can
1348 use to identify the command replies with the identifier.
1350 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Added silc_server_get_client_route to resolve the route to
1353 the client indicated by the client ID. Affected file is
1356 * Added silc_server_relay_packet as general function to relay
1357 packet to arbitrary destination. This deprecates functions
1358 like _send_private_message_key, _relay_notify etc. Affected
1359 file is silcd/packet_send.[ch].
1361 Removed silc_server_send_key_agreement,
1362 silc_server_send_private_message_key and
1363 silc_server_packet_relay_notify functions from the file
1364 silcd/packet_send.[ch].
1368 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1369 server. Affected file silcd/packet_receive.[ch].
1371 * Implemented the KILL command to the client. Implemented the
1372 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1373 Affected files lib/silcclient/command[_reply].c and
1374 lib/silcclient/client_notify.c. Implemented the KILL notify
1375 printing in the user inteface.
1377 * Fixed a lot silc_parse_nick memory leaks from the client
1378 library in the file lib/silcclient/command.c.
1380 * Changed the silc_server_send_notify_on_channels's `sender'
1381 argument from SilcSocketConnection to SilcClientEntry to
1382 check the sender as entry and not as connection object and not
1383 to send to the client provided as argument. The affected file
1384 is silcd/packet_send.[ch].
1386 * The notify packets that are destined directly to the client used
1387 to not to be processed by the server. Now changed that and the
1388 server processes all notify packets. After relaying the packet
1389 to the client the notify packet is processed in the server.
1391 * The silc_server_free_client_data now checks whether there is
1392 pending outgoing traffic for the client and purges the data to
1393 the network before removing the client entry.
1395 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1398 an client is killed from the SILC Network. Updated the protocol
1401 Added new function silc_server_send_notify_killed to the
1402 silcd/packet_send.[ch].
1404 * Added function silc_server_packet_relay_notify to relay notify
1405 packets that are destined directly to a client. In this case
1406 the server does not process the notify packets but merely relays
1407 it to the client. Affected file silcd/packet_send.[ch].
1409 Added also silc_server_packet_process_relay_notify to check
1410 whereto relay the notify. Affected file is
1411 silcd/packet_receive.[ch].
1413 * Implemented the KILL command to the server.
1417 * Added the backup schema desgined last fall to the protocol
1418 specs for everyone to see. The specification is in the
1419 *-spec-xx.txt draft and the packet type definitions for the
1420 backup routers is in *-pp-xx.txt draft. Thusly, added also
1421 new packet type SILC_PACKET_CELL_ROUTERS.
1423 * A big security problem in the implementation discovered. The
1424 signoff of an client did not cause new channel key generation
1425 which it of course should've done. The channel keys must be
1426 always re-generated when client leaves (or signoffs) the channel.
1427 The silc_server_remove_from_channels funtion now handles
1428 the channel key re-generation.
1430 * Added `sender' argument to the silc_server_send_notify_on_channels
1431 to not to send the client provided as argument. Affected file
1432 silcd/packet_send.[ch].
1434 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Implemented OPER and SILCOPER commands into the server and
1439 * Added silc_auth_verify and silc_auth_verify_data to verify
1440 the authentication directly from the authentication payload.
1441 It supports verifying both passphrase and public key based
1442 authentication. Affected file lib/silccore/silcauth.[ch].
1444 * Added `hash' field to the SilcIDListData structure. It is the
1445 hash negotiated in the SKE protocol. Affected file is
1448 * Slight redesigning of the SilcAuthPayload handling routines.
1449 Do not send SilcPKCS but SilcPublicKey as argument.
1451 * Implemented the public key authentication support to the
1452 serverconfig. The public key is loaded from the provided path
1453 and saved as authentication data to void * pointer. Thus,
1454 changed the unsigned char *auth_data to void *auth_data;
1456 * Fixed SHUTDOWN command to send the reply before the server
1457 is shutdown. :) Affected file silcd/command.c.
1459 * Fixed fatal bug in CONNECT command. The hostname was invalid
1460 memory and server crashed. Affected file silcd/command.c.
1462 * Fixed fatal bug in CLOSE command. The server_entry became
1463 invalid but was referenced later in the command. Affected file
1466 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Fixed fatal bug in failure packet handling. Server ignored
1469 the failure and thus crashed when it came.
1473 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1475 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1476 that the command may be executed only once in (about) 2 seconds.
1477 The old SILC_CF_LAG flag is same but allows command bursts up
1478 to five before limiting.
1480 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1481 server code. Various commands now includes the CF_LAG_STRICT
1482 flag to disallow any kind of miss-use of the command.
1484 * Fixed the silc_buffer_unformat to not to allocate any data
1485 if the length of the data is zero. It used to allocate the
1486 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1488 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1490 * Changed the format of AdminConnection configuration section
1491 in the server. Added username of the admin to the format.
1492 Affected files silcd/serverconfig.[ch].
1494 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1495 to return admin configuration data by host, username and/or
1498 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Implemented WHOWAS command to the server. Added the functions:
1502 silc_server_command_whowas_parse,
1503 silc_server_command_whowas_send_reply,
1504 silc_server_command_whowas_from_client and
1505 silc_server_command_whowas_from_server
1507 * Added <Client ID> argument to the WHOWAS command reply. Updated
1508 the protocol specs accordingly.
1510 * Implemented WHOWAS command and command_reply to the client
1513 Implemented the WHOWAS printing on the user interface.
1515 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Added new argument to the WHOWAS command reply, the real name.
1518 It is an optional argument. Updated the protocol specs.
1520 * Added SilcIDCacheDestructor callback that is registered when
1521 the SilcIDCache is allocated. The callback is called when
1522 an cache entry in the ID Cache expires, or is purged from the
1523 cache. Added into lib/silccore/idcache.[ch].
1525 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1526 to destruct the client entries when the cache entry expires.
1527 Other ID Cache's in server and in the client library ignores
1530 * If the ID Cache entry's `expire' field is zero then the entry
1531 never expires. Added boolean `expire' argument to the
1532 silc_idcache_add function in the lib/silccore/idcache.[ch].
1533 If it is TRUE the default expiry value is used.
1535 * Added silc_server_free_client_data_timeout that is registered
1536 when client disconnects. By default for 5 minutes we preserve
1537 the client entry for history - for WHOWAS command.
1539 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1541 * Added support to the server to enforce that commands are not
1542 executed more than once in 2 seconds. If server receives
1543 commands from client more frequently, timeout is registered
1544 to process the commands. Affected file silcd/command.c.
1545 Added new function silc_server_command_process_timeout.
1547 * Changed NICK_NOTIFY handling in client library to check that
1548 if the client's nickname was changed, so there is no need to
1549 resolve anything from the server.
1551 * Removed error printing from the WHOIS and IDENTIFY commands.
1552 If error occurs then it is ignored silently in the client library.
1553 The application, however, may map the received error to
1554 human readable error string. The application currently maps
1555 the NO_SUCH_NICKNAME error to string.
1557 * Made the command status message public to the application. Moved
1558 them from lib/silcclient/command_reply.c to
1559 lib/silcclient/command_reply.h. The application can map the
1560 received command status to the string with the
1561 silc_client_command_status_message function.
1563 * Added check to the server to check that client's ID is same
1564 as the Source ID in the packet the client sent. They must
1567 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Added dist-bzip hook to the Makefile.am to make bzip2
1570 compressed distributions.
1572 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Server now enforces the maximum length for the nickname and
1575 the channel as protocol specification dictates. 128 bytes for
1576 nickname and 256 bytes for channel name.
1578 * Moved the WHOIS printing to the application. The client libary
1579 does not print out the WHOIS information anymore, the application
1580 must do it. Renamed silc_client_command_reply_whois_print to
1581 the silc_client_command_reply_whois_save.
1583 The client's idle time is also sent to the application now, and
1584 the idle is shown on screen.
1586 * Added silc_client_command_reply_identify_save to save the
1587 received IDENTIFY entries.
1589 * Do not check for channel private keys in message sending and
1590 reception if the channel does not have the PRIVKEY mode set.
1591 Affected file lib/silclient/client_channel.c.
1593 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1596 just surfaced after chaning the JOIN procedure.
1598 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Added silc_client_get_clients_by_list to get client entries
1601 from Client ID list, that is returned for example by JOIN
1602 and USERS command replies. The application should use this
1603 function for example when JOIN command reply is received to
1604 resolve the clients already on the channel (library does not
1605 do that anymore as USERS command reply is not used in the JOIN
1606 procedure anymore). Affected files lib/silcclient/silcapi.h and
1607 lib/silcclient/idlist.c.
1609 * JOIN command reply and USERS command reply returns now SilcBuffer
1610 pointers instead of unsigned char pointers when returning
1611 the client list and mode list.
1613 * Added <Client ID> argument to the JOIN command reply, mainly
1614 for the server to identify for which client the command was
1615 originally sent. Updated protocol specs accordingly.
1617 * Added SilcDlist private_key pointer to the SilcChannelEntry
1618 in the client to support the channel private keys. Affected
1619 file is lib/silcclient/idlist.h.
1621 * Added SilcChannelPrivateKey argument to the function
1622 silc_client_send_channel_message so that application can choose
1623 to use specific private ke if it wants to. If it is not provided,
1624 the normal channel key is used, unless private keys are set.
1625 In this case the first (key that was added first) is used
1626 as the encryption key.
1628 * Implemented the support for channel private key handling.
1629 Implemented the following functions:
1631 silc_client_add_channel_private_key,
1632 silc_client_del_channel_private_keys,
1633 silc_client_del_channel_private_key,
1634 silc_client_list_channel_private_keys and
1635 silc_client_free_channel_private_keys
1637 Affected file lib/silcclient/client_channel.c.
1639 * Added the support for the private keys in the channel message
1640 sending and encryption and in the message reception and
1641 decryption. Affected funtions are
1642 silc_client_send_channel_message and silc_client_channel_message.
1644 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1646 * Added SKE's key verify callback to the client library's
1647 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1649 * Removed the statement that server (or router) must send USERS
1650 command reply when joining to the channel so that the client
1651 knows who are on the channel. Instead, the client list and
1652 client's mode list is now sent in the JOIN command reply to the
1653 client who joined channel. This is better solution.
1655 * Added function silc_server_get_users_on_channel and function
1656 silc_server_save_users_on_channel to the silcd/server.[ch].
1658 * Removed function silc_server_command_send_users from the
1661 * Do not show topic on the client library anymore. The topic is
1662 sent in the command reply notify to the application and the
1663 application must show the topic now.
1665 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1667 * Added client searching by nickname hash into the IDENTIFY and
1668 WHOIS commands in the server as they were clearly missing from
1669 them. Affected file is silcd/command.c.
1671 * Fixed a bug in private message receiving in the client library.
1672 The remote ID was freed and it wasn't supposed, now it is
1675 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Minor fix to the channel payload; allocate the data area, as it
1678 needs to be of specific length.
1680 * If the key agreement port is zero then the operating
1681 system will define the bound port. Affected files are
1682 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1684 * Added new function silc_channel_payload_decrypt into the file
1685 lib/silccore/silcchannel.[ch].
1687 * Moved the channel message etc, check from silc_packet_decrypt
1688 to applications. The library calls now a generic
1689 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1690 when the packet is either normal or special. This was done to
1691 allow more wide range of checking that was not allowed when
1692 the code was in library. Now applications can do virtually any
1693 checks to the packet and return to the library the decision how
1694 the packet should be processed. Affected files are
1695 lib/silccore/silcpacket.[ch].
1697 Added silc_server_packet_decrypt_check to the server and
1698 silc_client_packet_decrypt_check to the client library.
1700 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1701 to send with specified source and destination information.
1703 * Channel message delivery between routers was broken after the
1704 channel key distribution was fixed earlier. The channel key
1705 was used be to distributed to other routers as well which is not
1706 allowed by the protocol. Now this is fixed and channel keys
1707 really are cell specific and the channel message delivery between
1708 routers comply with the protocol specification.
1710 * Fixed various commands in server to check also the global list
1711 for the channel entry and not just the local list. The affected
1712 file silcd/command.c.
1714 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Added assert()s to buffer formatting and unformatting routines
1717 to assert (if --enable-debug) when error occurs. Affected
1718 file: lib/silcutil/silcbuffmt.c.
1720 * Changed to auto-reconnect to check whether the remote host is
1721 router and register the re-connect timeout if it is. It used
1722 to check that whether we are normal server, but router must do
1723 auto-reconnect with another router as well. Affected file
1726 * Removed the [<key len>] option from CMODE command as the cipher
1727 name decides the key length, nowadays. See the defined ciphers
1728 from the protocol specification.
1730 * Added [<hmac>] option to the CMODE command to define the HMAC
1731 for the channel. Added SILC_CMODE_HMAC channel mode.
1733 * Added [<hmac>] option for the JOIN command so that user can
1734 select which HMAC is used to compute the MACs of the channel
1737 * Added Hmac field to the Channel Message Payload. The integrity
1738 of plaintext channel messages are now protected by computing
1739 MAC of the message and attaching the MAC to the payload. The
1740 MAC is encrypted. Now, it is clear that this causes some
1741 overhead to the size of the packet but rationale for this is that
1742 now the receiver can verify whether the channel message decrypted
1743 correctly and also when private keys are set for the channel the
1744 receiver can decrypt the packet with several keys and check from
1745 the MAC which key decrypted the message correctly.
1747 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1748 lib/silccrypt/silccipher.[ch].
1750 * Added silc_hash_len to return the digest length into the
1751 lib/silcrypt/silchash.[ch].
1753 * Rewrote parts of Silc Channel Payload interface in the
1754 lib/silccore/silcchannel.[ch]. The encode function now also
1755 encrypts the packet and parse function decrypts it.
1757 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1759 * Fixed a minor formatting bug in the SKE's key material processing.
1760 It actually might have processed the keys wrong way resulting
1763 * Redefined the mandatory HMAC algorithms and added new algorithms.
1764 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1765 and hmac-md5 truncated to 96 bits. The mandatory is now
1766 hmac-sha1-96. Rest are optional (including the one that used
1767 to be mandatory). Rationale for this is that the truncated HMAC
1768 length is sufficient from security point of view and can actually
1769 make the attack against the HMAC harder. Also, the truncated
1770 HMAC causes less overhead to the packets. See the RFC2104 for
1773 * Added new [hmac] configuration section. The SKE used to use
1774 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1775 is of course wrong. The official names that must be proposed in
1776 the SKE are the ones defined in the protocol specification
1777 (hmac-sha1-96 for example). The user can configure any hmac
1778 using any hash function configured in the [hash] section. At
1779 least, the mandatory must be configured.
1781 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1783 * Added HMAC list to the SKE proposal list. It has now both
1784 hash algorithm list and HMAC list. This makes the protocol
1785 incompatible with previous versions. The SKE now seems to work
1786 the way it is supposed to work, for the first time actually.
1788 * Defined plain Hash algorithms to the protocol specification.
1791 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Implemented support for key agreement packets into the server.
1794 Added functions silc_server_key_agreement and
1795 silc_server_send_key_agreement. Other than these functions,
1796 server has nothing to do with this packet.
1798 * Added support for private message key packets into the server.
1799 Added functions silc_server_private_message_key and
1800 silc_server_send_private_message_key.
1804 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1805 called in the protocol's final callback instead in the END
1806 protocol state. This makes a little more sense and in the same
1807 time in client we can use the same protocol routines for normal
1808 key exchange and to key agreement packet handling as well.
1810 * Added to both client's and server's KE protocol context the
1811 SilcSKEKeyMaterial pointer to save the key material. We will
1812 bring the key material to the protocol's final callback by doing
1813 this. The final callback must free the key material.
1815 * Added SKE's packet_send callback into client's KE protocol
1816 context so that the caller can choose what packet sending function
1817 is used. This way we can use different packet sending when
1818 doing normal SKE when doing key agreement packet handling (in
1819 the key agreement packet handling we do not want to encrypt
1822 * Implemented the responder side of the key agreement routines
1823 in the client. The client can now bind to specified port and
1824 accept incoming key negotiation. The key material is passed
1825 to the application after the protocol is over.
1827 * Implemented the processing of incoming Key Agreement packet
1828 in the client. Added function silc_client_key_agreement to
1831 * Implemented the intiator side of the key agreement routines
1832 in the client. The client can now initiate key agreement with
1833 another remote client. The key material is passed to the
1834 application after the protocol is over.
1836 * Created client_keyagr.c to include all the key agreement
1839 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1840 SILC_TASK_CALLBACK except that it is not static.
1842 * Created client_notify.c and moved the Notify packet handling
1843 from the client.[ch] into that file.
1845 * Created client_prvmsg.c and moved all private message and
1846 private message key routines from the client.[ch] into that file.
1848 * Create client_channel.c and moved all channel message and
1849 channel private key routines from the client.[ch] into that file.
1851 * Changed silc_client_get_client_by_id_resolve to resolve with
1852 WHOIS command instead of IDENTIFY command, in the file
1853 lib/silclient/idlist.c.
1855 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Implemented the SKE's responder side to the Client library.
1859 * When FAILURE is received to the protocol do not trust it
1860 blindly. Register a timeout to wait whether the remote closes
1861 the connection as it should do it, only after that process the
1862 actual failure. This was changed to both client and server.
1864 * Added client_internal.h to include some of the structures
1865 there instead of client.h in lib/silcclient/.
1867 * Added function silc_task_unregister_by_callback to unregister
1868 timeouts by the callback function.
1870 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Some "Incomplete WHOIS info" errors has been appearing on the
1873 log files. Took away the entry->userinfo check from WHOIS
1874 reply sending. The entry->userinfo is now " " if client did not
1875 provide one. I thought this was fixed earlier but something
1876 is wrong still. Let's see if the error still appears.
1878 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Fixed a minor bug in the login when the channel key is
1881 re-generated in the server. It used to generate the key in
1882 wrong order and thus caused problems in the channel traffic.
1884 * Fixed a minor bug in channel key distsribution after
1885 KICK command. The key was not sent to the router even though
1888 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added silc_ske_process_key_material_data as generic routine
1891 to process any key material as the SILC protocol dictates. The
1892 function is used by the actual SKE library but can be used by
1893 applications as well. This relates to the private message keys
1894 and the channel private keys since they must be processed the
1895 same way the normal SILC session keys. The protocol dictates
1896 this. Affected files: lib/silcske/silcske.[ch].
1898 Added also silc_ske_free_key_material to free the
1899 SilcSKEKeyMaterial structure.
1901 * Defined silc_cipher_set_key function to set the key for
1902 cipher without using the object's method function. The affected
1903 files: lib/silccrypt/silccipher.[ch].
1905 * Implemented silc silc_client_add_private_message_key,
1906 silc_client_add_private_message_key_ske,
1907 silc_client_del_private_message_key,
1908 silc_client_list_private_message_keys and
1909 silc_client_free_private_message_keys functions in the
1912 Added functions silc_client_send_private_message_key to send
1913 the Private Message Key payload and silc_client_private_message_key
1914 to handle incoming Private Message Key payload.
1916 * Added Cipher field to the Private Message Key payload to set
1917 the cipher to be used. If ignored, the default cipher defined
1918 in the SILC protocol (aes-256-cbc) is used.
1920 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Removed lib/silcclient/ops.h file.
1924 Redefined parts of the SILC Client Library API. Created new
1925 file silcapi.h that deprecates the ops.h file and defines the
1926 published Client Library API. Defined also private message key
1927 API and channel private key API into the file.
1929 This is the file that the application must include from the
1930 SILC Client Library. Other files need not be included by
1931 the application anymore.
1933 * Added new key_agreement client operation callback and also
1934 defined the Key Agreement library API for the application.
1936 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1939 is used by clients to request key negotiation between another
1940 client in the SILC network. If the negotiation is started it
1941 is performed using the SKE protocol. The result of the
1942 negotiation, the secret key material, can be used for example
1943 as private message key.
1945 Implemented the Key Agreement payload into the files
1946 lib/silccore/silauth.[ch].
1948 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Redefined ciphers for the SILC protocol. Added some new ciphers
1951 and defined the key lengths for the algorithms. Changed the
1952 code accordingly. The default key length is now 256 bits.
1954 * Fixed SKE key distribution function silc_ske_process_key_material
1955 when the key length is more than 128 bits. The default key
1956 length in SILC is now 256 bits.
1958 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1959 to indicate unsupported algorithm.
1961 * Renamed rijndael.c to aes.c and all functions as well.
1963 * Fixed a long standing channel key setting bug in client library.
1964 Weird that it has never surfaced before.
1966 * Fixed bug in channel deletion. If the entire channel is removed
1967 then it must also delete the references of the channel entry
1968 from the client's channel list as the client's channel entry and
1969 the channel's client entry share same memory.
1971 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1973 * Implemented CONNECT and SHUTDOWN commands in the client.
1975 * Implemented CLOSE command to the client.
1977 * Added the function silc_idlist_find_server_by_name into the
1978 files silcd/idlist.[ch].
1980 Added the function silc_idlist_find_server_by_conn into the
1981 files silcd/idlist.[ch].
1983 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * DIE command was renamed to SHUTDOWN. Updated the both code
1988 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1989 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1991 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1994 * Added function silc_server_create_connection function to create
1995 connection to remote router. My server implementation actually
1996 does not allow router to connect to normal server (it expects
1997 that normal server always initiates the connection to the router)
1998 so the CONNECT command is only good for connecting to another
2001 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2003 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2004 or some other client was kicked from the channel.
2006 Implemented the handling of the notify type to both client
2009 Implemented silc_server_send_notify_kicked to send the KICKED
2010 notify. It is used to send it to the server's primary router.
2012 * Implemented the KICK command into server and client.
2014 * Added `query' argument to the silc_idlist_get_client function
2015 to indicate whether to query the client from server or not if
2018 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2019 to indicate that the client is not channel founder.
2023 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Removed the rng context from SilcPacketContext structure and
2026 changed that the packet routine uses the Global RNG API.
2028 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Added support for quit message that client can "leave" on the
2031 channel when it quits the SILC. It is ditributed inside the
2032 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2034 Added silc_server_free_client_data that will take the
2035 signoff message as argument.
2037 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2039 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Updated parts of the protocol specification to keep it up
2044 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2046 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2047 payloads in one packet.
2049 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2050 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2051 use now the new List flag.
2053 * Also deprecated the following packet types: REPLACE_ID,
2054 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2056 * Added list support for Notify packet in server.
2058 * Added silc_server_send_notify_channel_change to send the
2059 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2060 the silc_server_send_replace_id.
2062 * Added silc_server_send_notify_nick_change to send the
2063 NICK_CHANGE notify type. Deprecates the function
2064 silc_server_send_replace_id.
2066 * Added silc_server_send_notify_join to send the JOIN notify type.
2067 Deprecates the function silc_server_send_new_channel_user.
2069 * Added silc_server_send_notify_leave to send LEAVE notify type.
2070 Deprecates the function silc_server_send_remove_channel_user.
2072 * Added silc_server_send_notify_cmode and
2073 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2074 types. Deprecates the silc_server_send_set_mode function.
2076 * Added SERVER_SIGNOFF notify type to indicate that server has
2077 quit. This means that all clients on the channel from that
2078 server will drop. This can be also used when netsplit happens.
2080 Deprecated REMOVE_ID packet type since it is not needed anymore
2083 Added silc_server_send_notify_server_signoff to send the
2084 SERVER_SIGNOFF notify type. Deprecates the function
2085 silc_server_send_remove_id.
2087 Added also silc_server_send_notify_signoff to send the
2088 SIGNOFF notify type.
2090 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2091 SILC protocol from this day on. Changed the protocol
2092 specification as well.
2094 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2095 notify type. It is used between routers to notify about
2096 topic changes on a channel.
2098 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2101 * Partly updated the protocol specification to comply with the
2102 changes now made. It is still though a bit outdated.
2104 * The JOIN notify type now takes one extra argument <Channel ID>.
2105 The packet used to be destined to the channel but now the
2106 JOIN type may be sent as list thus it is impossible to
2107 destine it to any specific channel. By adding this argument
2108 it is again possible.
2110 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2112 * Added CREDITS file. The CHANGES and CREDITS file will appear
2113 in the distribution as well.
2115 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2118 types in the server's silcd/packet_receive.c.
2120 * Implemented CMODE and CUMODE to work in router environment.
2122 * Fixed minor encoding and decoding buglet from the
2123 lib/silccore/silcmode.c.
2125 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2128 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2130 * Changed all SilcConfigServer* and silc_config_server* to
2131 SilcServerConfig* and silc_server_config*, respectively.
2134 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2136 * Associated the ID (client or server ID) to the Authentication
2137 Payload to avoid any possibility of forging. Updated the
2138 protocol specification and the code accordingly.
2140 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * The RSA key length is now save to the RsaKey context in the
2143 key generation process in lib/silccrypt/rsa.c. The key length
2144 is now used to figure out the maximum size of the block allowed
2145 to be encrypted/signed.
2147 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2148 is equivalent to the silc_mp_mp2bin but does not allocate any
2151 * Changed silc_mp_mp2bin API to take length argument. If it is
2152 non-zero then the buffer is allocated that large. If zero, then
2153 the size is approximated using silc_mp_sizeinbase, which however
2156 * Created Global RNG API which is global RNG that application can
2157 initialize. After initializing, any routine anywhere in the
2158 code (including library) can use RNG without allocating a new
2159 RNG object. This was done to allow this sort of use of the
2160 RNG in code that has no chance to allocate RNG object. All
2161 applications currently allocate this and many routines in the
2162 library use this. Affected file lib/silccrypt/silcrng.[ch].
2164 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2165 it to use the Global RNG API.
2167 * Defined Authentication Payload into protocol specification that
2168 is used during SILC session to authenticate entities. It is
2169 used for example by client to authenticate itself to the server
2170 to obtain server operator privileges.
2172 Implemented this payload into the lib/silccore/silcauth.[ch].
2173 Implemented also routines for public key based authentication
2174 as the new protocol specification dictates.
2176 Moved definitions of different authentication methods from
2177 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2179 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2180 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2181 silc_pkcs_verify_with_hash functions into the file
2182 lib/silccrypt/silcpkcs.[ch].
2184 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * The client entry's userinfo pointer must be always valid.
2187 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2188 will fail since it requires the userinfo. Now, the userinfo
2189 is allocated as "" if actual userinfo does not exist. Actually,
2190 it must exist and it is totally Ok to drop client connections
2191 that does not announce the userinfo. However, we will make
2192 this workaround for now.
2194 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2195 to return the remote port by socket.
2197 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2199 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2200 SILC_SERVER_PENDING_EXEC and added an new macro
2201 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2202 data or when error occurs while processing the pending command.
2204 Added new argument `destructor' into silc_server_command_pending
2205 and to the SilcServerCommandPending object. This destructor is
2206 now called after calling the pending callback or if error occurs
2207 immediately. If error occurs the actual pending callback won't
2208 be called at all - only the destructor. The destructor may be
2209 NULL if destructor is not needed.
2211 All this applies for client library code as well. Similar
2212 changes were made there as well for the pending commands.
2214 In the client, the application must now allocate the
2215 SilcClientCommandContext with the silc_client_command_alloc
2218 * Added reference counter to the SilcServerCommandContext. Added
2219 function silc_server_command_alloc and silc_server_command_dup
2222 Same type of functions added to the client library for the same
2225 * Removed the cmd_ident from IDListData away since it is now
2226 global for all connections. It is the command identifier used
2227 in command sending and with pending commands. The affected file
2230 * Added reference counter to the SilcSocketConnection objecet to
2231 indicate the usage count of the object. The object won't be
2232 freed untill the reference counter hits zero. Currently only
2233 server uses this, and client ignores it. The client must be
2234 set to use this too later. The affected files are
2235 lib/silccore/silcsockconn.[ch]. Added also the function
2236 silc_socket_dup to increase the reference counter.
2238 This was mainly added because it is possible that the socket
2239 is removed underneath of pending command or other async
2240 operation. Now it won't be free'd and proper DISCONNECTING
2241 flags, etc. can be set to avoid sending data to connection that
2242 is not valid anymore.
2244 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2245 the connection. After that it sets SILC_SET_DISCONNECTED.
2246 It is, however, possible that the socket data is not still freed.
2247 The silc_server_packet_process now checks that data is not
2248 read or written to connection that is DISCONNECTED. The socket
2249 get's freed when the reference counter hits zero.
2251 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Changed the client operation API: channel_message operation's
2254 `sender' is now the client entry of the sender, not the nickname
2255 and the `channel' is the channel entry, not the channel name.
2257 In the private_message operation the `sender' is now also the
2258 client entry of the sender not the nickname.
2260 Affected file is lib/silcclient/ops.h and all applications
2261 using the client operations.
2263 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2265 * Moved the calling of ops->connect() from connect_to_server_final
2266 into receive_new_id functin since that is the point when the
2267 client is actually allowed to send traffic to network. The
2268 affected file is lib/silcclient/client.c.
2270 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2272 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2273 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2274 (if needs broadcasting) instead of broadcasting the packets one
2275 by one which would make a burst in the network traffic.
2277 * Added `broadcast' argument to the functions in silcd/server.[ch]
2278 silc_server_create_new_channel[_with_id] to indicate whether
2279 to send New Channel packet to primary router.
2281 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added new function into the silcd/server.[ch] files:
2284 silc_server_create_new_channel_with_id to create new channel with
2285 already existing Channel ID.
2287 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2288 lib/silccore/silcpacket.h. This packet is used t send list of
2289 Set Mode payloads inside one packet. Server uses this to set
2290 the modes for the channels and clients on those channels, that it
2291 announced to the router when it connected to it. The protocol
2292 specification has been updated accordingly.
2294 * The silc_server_new_channel did not handle the packet coming
2295 from normal server as it normally does not send that. However,
2296 when it announces its channels it does send it. Implemented
2297 the support for that.
2299 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2300 into the file lib/silccore/id.h.
2302 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2304 * Fixed memory leaks in the functions silc_idlist_del_client,
2305 silc_idlist_del_channel and silc_idlist_del_server in the file
2306 silcd/idlist.c. All of those leaked like a sieve.
2308 * Fixed some small memory leaks in the client's function
2309 silc_client_notify_by_server.
2311 * Added functions into silcd/server.c: silc_server_announce_clients,
2312 silc_server_announce_channels and silc_server_announce_server.
2313 These functions are used by normal and router server to announce
2314 to its primary router about clients, channels and servers (when
2315 router) that we own. This is done after we've connected to the
2318 These functions effectively implements the following packet types:
2319 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2320 and SILC_PACKET_NEW_ID_LIST.
2322 * Added new functions into the silcd/packet_receive.[ch]:
2323 silc_server_new_id_list, silc_server_new_channel_list and
2324 silc_server_new_channel_user_list to handle the incoming
2325 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2327 * Added support of changing Channel ID in the function
2328 silc_server_replace_id. If the server that announces a channel
2329 to the router already exists in the router (with same name but
2330 with different Channel ID), router is responsible to send
2331 Replace ID packet to the server and force the server to change
2332 the Channel ID to the one router has.
2334 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2335 client that the Channel ID has been changed by the router. The
2336 normal server sends this to the client. Client must start using
2337 the new Channel ID as the channel's ID.
2339 Implemented handling of this new type into lib/silcclient/client.c
2340 into the function silc_client_notify_by_server.
2342 * Added new function silc_idlist_replace_channel_id into the files
2343 silcd/idlist.[ch] to replace the Channel ID.
2345 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2347 * Call silc_server_command_identify_check always when processing
2348 the IDENTIFY command in silcd/command.c
2350 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2353 send keepalive packets. The packet can be sent by clients,
2354 servers and routers.
2356 Added function silc_socket_set_heartbeat into the file
2357 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2358 If not set, the heartbeat is not performed. The actual
2359 heartbeat is implemented in the low level socket connection
2360 library. However, application is responsible of actually
2363 Added silc_server_send_heartbeat to send the actual heartbeat
2364 packet into silcd/packet_send.[ch]. Server now performs
2365 keepalive with all connections.
2367 * Added silc_task_get_first function into lib/silcutil/silctask.c
2368 to return the timeout task with shortest timeout. There was a bug
2369 in task unregistration that caused problems. TODO has been
2370 updated to include that task system must be rewritten.
2372 * The client library will now resolve the client information when
2373 receiving JOIN notify from server for client that we know but
2374 have incomplete information.
2376 * Rewrote parts of silc_server_remove_from_channels and
2377 silc_server_remove_from_one_channel as they did not remove the
2378 channel in some circumstances even though they should've.
2380 * Encryption problem encountered in server:
2382 The LEAVE command used to send the Channel Key packet to the
2383 router immediately after generating it. However, the code
2384 had earlier sent Remove Channel user packet but not immediately,
2385 ie. it was put to queue. The order of packets in the router
2386 was that Channel Key packet was first and Remove Channel User
2387 packet was second, even though they were encrypted in the
2388 reverse order. For this reason, MAC check failed. Now, this
2389 is fixed by not sending the Channel Key packet immediately but
2390 putting it to queue. However, this is more fundamental problem:
2391 packets that are in queue should actually not be encrypted
2392 because packets that are sent immediately gets encrypted
2393 actually with wrong IV (and thus MAC check fails). So, packets
2394 that are in queue should be encrypted when they are sent to
2395 the wire and not when they put to the queue.
2397 However, the problem is that the current system has not been
2398 designed to work that way. Instead, the packet is encrypted
2399 as soon as possible and left to the queue. The queue is then
2400 just purged into wire. There won't be any fixes for this
2401 any time soon. So, the current semantic for packet sending
2404 o If you send packet to remote host and do not force the send
2405 (the packet will be in queue) then all subsequent packets to the
2406 same remote host must also be put to the queue. Only after the
2407 queue has been purged is it safe again to force the packet
2410 o If you send all packets immediately then it safe to send
2411 any of subsequent packets through the queue, however, after
2412 the first packet is put to queue then any subsequent packets
2413 must also be put to the queue.
2415 Follow these rules and everything works fine.
2417 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Added new function silc_server_remove_clients_by_server to
2420 remove all client entries from ID list when the server connection
2421 is lost. In this case it is also important to invalidate all
2422 client entires as they hold the invalid server entry. This
2423 fixes fatal bug when server has lost connection and will reconnect
2426 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2428 * Made some sanity checks to silc_server_daemonise like to check
2429 whether the requested user and group actually exists.
2431 * Added sanity check to SKE's silc_ske_responder_finish to check
2432 that the public and private key actually is valid.
2434 * Invalidate the client's nickname when receiving Replace ID
2435 packet and the Client ID is being replaced. This means that the
2436 server will query the nickname if someone needs it (client)
2439 * Sort the ID Cache in client library when the ID Cache data
2440 has changed (needs sorting).
2442 * Do not allow for SILC client to create several connections to
2443 several servers. The client does not support windows right now
2444 and generating multiple connections causes weird behaviour.
2446 Irssi-silc client does support windows and can handle several
2447 connections without problems, see: www.irssi.org and SILC plugin.
2449 * Fixed some places where client was added to the IDList. The
2450 rule of thumb is following (in order to get everything right):
2451 If the client is directly connected local client then the
2452 `connection' argument must be set and `router' argument must be
2453 NULL to silc_idlist_add_client function. If the client is not
2454 directly connected client then the `router' argument must
2455 bet set and the `connection' argument must be NULL to the
2456 silc_idlist_add_client function.
2458 * The funtion silc_server_packet_send_local_channel actually did
2459 not check whether the client was locally connected or not. It
2460 does that now. Fixed a bug related to LEAVE command.
2462 * Fixed Remove Channel User payload parsing bug in server's
2463 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2465 * The server's silc_server_save_channel_key now checks also the
2466 global ID list for the channel as it might not be in the local
2467 list. Fixed a bug related to LEAVE command.
2469 * Is this the end of the [<unknown>] buglet that has been lurking
2470 around for a long time? A little for loop fix in server's
2471 silc_server_command_whois_parse that is used by both IDENTIFY
2472 and WHOIS command. At least, this was a clear bug and a cause
2473 of one type of [<unknown>] buglet.
2475 * WHOIS and IDENTIFY commands call the function
2476 silc_server_command_[whois/identify]_check function even if
2477 we are not router server.
2479 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2481 * Added --with-gmp configuration option. If set the GMP
2482 is always compiled in the SILC source tree. If not set then
2483 it is checked whether the system has the GMP3 installed. If
2484 it has then the GMP won't be compiled (the system's headers
2485 and library is used), if it doesn't have it then the GMP is
2486 compiled in the SILC source tree.
2488 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * Changed RSA private exponent generation to what PKCS #1
2491 suggests. We try to find the smallest possible d by doing
2492 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2493 not security fix but optimization.
2495 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2497 * Added new config entry [Identity] to fork the server and run
2498 it as specific user and group. A patch from Bostik.
2500 * Imported Dotconf configuration library into lib/dotconf.
2501 This will be used to create the SILC configuration files later.
2502 It will appear in the distsribution after this commit.
2504 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * A big code auditing weekend happening. Auditing code for
2507 obvious mistakes, bugs and errors. Also, removing any code
2510 Removed files for being obsolete:
2512 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2513 inline in the file lib/silcutil/silcbuffer.h)
2515 o lib/silcutil/silcbufutil.c (the header has inline versions)
2517 Changed code to fix possible error conditions:
2519 o The buffer formatting routines now check that the destination
2520 buffer really has enough space to add the data. This applies for
2521 both buffer formatting and unformatting
2522 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2523 unformatting was changed to accomodate following rules:
2524 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2525 sent to the function while XXX_*STRING will not allocate or copy
2526 the data into the buffer. Instead it sets the pointer from the
2527 buffer into the pointer sent as argument (XXX_*STRING used to
2528 require that the pointer must be allocated already). This change
2529 makes this whole thing a bit more consistent and more optimized
2530 (note that the data returned in the unformatting with XXX_*STRING
2531 must not be freed now). The routines return now -1 on error.
2533 o Tried to find all code that use buffer_format and buffer_unformat
2534 and added return value checking to prevent formatting and
2535 especially unformatting errors and possible subsequent fatal
2538 o Changed ske->x and ske->KEY to mallocated pointers in
2539 lib/silcske/silcske.h. Fixed possible data and memory leak.
2541 o Added return value checking to all *_parse* functions. Fixed
2542 many memory leaks as well.
2544 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2545 so that buffer overflows would not happen. All code now also
2546 checks the return value as it can fail.
2548 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2550 * Added reconnection support to server if the normal server looses
2551 its connection to the router (for example if router is rebooted).
2552 The server performs normal reconnection strategy implemented
2553 to the server. Affected file silcd/server.c.
2555 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2557 * Added new packet type SILC_PACKET_SET_MODE that is used to
2558 distribute the information about changed modes (for clients,
2559 channels and clients channel modes) to all routers in the
2560 network. Updated the protocol specification accordingly.
2562 Added functions into silcd/packet_send.c and
2563 silcd/packet_receive.c: silc_server_send_set_mode,
2564 silc_server_set_mode.
2566 Added new files silcmode.[ch] into lib/silccore that implements
2567 the encoding and decoding of Set Mode Payload. Added new type
2568 SilcSetModePayload. Moved the definitions of different modes
2569 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2571 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2573 * Oops, a little mistake in server's connection authentication
2574 protocol. The protocol is not ended with FAILURE but with
2575 SUCCESS if the authentication is Ok. :) Affected file is
2578 * Implemented NICK_CHANGE notify handling in server in the file
2579 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2580 the local clients on the channel. After the changing nickname
2581 in router environment snhould work and the [<unknown>] nickname
2582 should appear no more.
2584 The silc_server_replace_id function that receives the Replace ID
2585 payload now sends the NICK_CHANGE notify type also in the file
2586 silcd/packet_receive.c
2588 * Changed WHOIS and IDENTIFY command to support the maximum amount
2589 of arguments defined in protocol specs (3328 arguments). This
2590 fixed a bug that caused problems when there were more than three
2593 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added extra parameter, command identifier, to the
2596 silc_client_send_command so that explicit command identifier
2599 Changed that ID list routines uses specific command identifier
2600 when sending WHOIS/IDENTIFY requests to the server so that they
2601 can be identified when the reply comes back.
2603 Affected files lib/silcclient/command.[ch],
2604 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2606 * Added `sender' argument to silc_server_packet_send_to_channel
2607 to indicaet the sender who originally sent the packet to us
2608 that we are now re-sending. Ignored if NULL. Affected file
2609 silcd/packet_send.[ch].
2611 * Added some server statistics support in silcd/server_internal.h
2612 SilcServerStatistics structure and around the server code. Also
2613 send some nice statistics information when client is connecting
2616 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2618 * Fixed channel ID decoding in server's JOIN command reply in
2619 silcd/command_reply.c
2621 * Fixed braodcasting of replace ID payload to not to send it if
2622 we are standalone server in silcd/packet_receive.c.
2624 * Fixed all channel message sending routines to not to send
2625 packets to clients that has router set, since they are routed
2626 separately in the same function earlier. Affects file
2627 silcd/packet_send.c and all channel packet sending functions.
2629 * In USERS reply, res_argv[i] are not allocated, the table
2630 is allocated. Thus changed that free the table, not its
2633 * In server's whois_check and identify_check if the client is
2634 locally connected do not send any WHOIS commands - they are not
2637 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Fixed some minor bugs in client when sending WHOIS command. The
2640 arguments was in wrong order.
2642 * Removed statis function add_to_channel from server in
2643 silcd/command.c that was previously used with the joining but
2646 * Tested USERS command in router environment successfully with two
2647 routers, two servers and two clients.
2649 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2651 * Reorganized the USERS command and command reply in client library
2652 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2653 When the command is given by user we register a pending command
2654 callback that will reprocess the command after the reply has been
2655 received from the server. When reprocessing the packet we then
2656 display the information. Thus, the USERS information is displayed
2657 now in the command callback instead of in the command reply
2658 callback. The processing of the command is same as previously
2659 when server has sent the command reply in the JOINing process.
2661 * Added to USERS command in silcd/command_reply.c to join the client,
2662 we didn't use to know about, to the channel after we've created
2663 a client entry for it. Also, for clienet we did know already still
2664 check whether it is on the channel or not and add it if not.
2666 * Removed silc_server_command_join_notify as the function and its
2669 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2671 * Changed the client's pending command handling to the same as the
2672 server's pending command handling. It is also now possible to
2673 execute command reply functions from other command reply
2674 function as the function callbacks for commands and command
2675 replies are one and same. The pending commands are not static
2676 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2677 in client connection context. Thus, pending commands are server
2678 connection specific as it is convenient.
2680 Changed the function silc_client_command_pending and
2681 silc_client_command_pending_del and added new function
2682 silc_client_command_pending_check. Removed the
2683 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2686 * Added cmd_ident, current command identifier, to the client
2687 connection context in lib/silcclient/client.h to keep track on
2688 command identifiers used in command sending. Client's command reply
2689 function handling now supports the mandatory command identifiers.
2691 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2692 funtions in client to fully support pending command callbacks.
2694 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2695 as one of the arguments to the application in the command reply
2698 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2699 before first releasing SILC but came back. Now it is removed again
2700 and should come back nomore. The FORWARDED flag was used only
2701 by the JOINing procedure by forwarding the command packet to router.
2702 Now, the JOINing procedure has been changed to more generic (due
2703 to various router environment issues) and FORWARDED is not needed
2704 anymore for anything. The protocol specification is yet to be
2707 Now, removed silc_server_packet_forward from server and the flag
2708 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2710 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2712 * Renamed NAMES command to USERS command. The NAMES was named that
2713 due to historical reasons. Now it is renamed. Also, rewrote
2714 parts of the USERS command. The nickname list is not sent anymore
2715 by the server. Only Client ID and mode lists are sent in the USERS
2716 command. Changed this also to the protocol specification.
2718 The client now resolves the names and stuff after it receives
2719 the USERS list from the server when joining to the channel.
2721 * WHOIS and IDENTIFY commands has been changed to support multiple
2722 Client ID's per command. One can now search for multiple users
2723 in the network by sending only one WHOIS or IDENTIFY command.
2724 Changed the code and the protocol specifications.
2726 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2727 uses silc_server_command_whois_parse to parse the request. */
2729 * If normal server, do not parse the WHOIS and IDENTIFY requests
2730 before sending it to the router. Saves some time.
2732 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * Fixed JOIN command on client library. Wrong number of arguments
2735 used to crash the client.
2737 * Added silc_server_channel_has_global function to check whether
2738 channel has global users or not.
2740 * Added silc_server_channel_has_local function to check whether channel
2741 has locally connected clients on the channel.
2743 * The silc_server_remove_from_one_channel now checks whether the
2744 channel has global users or not after given client was removed from
2745 the channel. It also checks whether the channel has local clients
2746 on the channel anymore. If it does not have then the channel entry
2747 is removed as it is not needed anymore.
2749 * The silc_server_notify now checks on JOIN notify whether the joining
2750 client is one of locally connected or global. If it is global then
2751 the channel has now global users on the channel and that is marked
2752 to the channel entry. Also, it now saves the global client to
2753 global list who is joining and JOINs it to the channel. This is
2754 for normal server, that is.
2756 Changed silc_server_send_notify_on_channel,
2757 silc_server_packet_relay_to_channel and
2758 silc_server_packet_send_to_channel check if we are normal server
2759 and client has router set (ie. global client) do not send the
2760 message to that client, as it is already routed to our router.
2762 * Implemented LEAVE notify type handling in silc_server_notify
2765 * Tested LEAVE command in router environment successfully. Tested
2766 with two routers, two servers and two clients.
2770 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2772 * Implemented SIGNOFF notify type handling in silc_server_notify
2775 * silc_server_remove_id now removes the client entry from all channels
2776 it has joined and thusly sends SIGNOFF notify type.
2778 * Rewrote the NAMES list generation in server by removing two excess
2779 loops. The lists are created now inside one loop.
2781 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2783 * silc_server_remove_channel_user checks now also global list
2784 for channel and client.
2786 * silc_server_new_channel_user checks now both local and global
2787 list for channel and client. Fixed a bug in client id decoding.
2788 Used to decode wrong buffer.
2790 * silc_server_channel_message checks now both local and global
2791 list for channel entry.
2793 * Tested channel joining (hence JOIN) in router environment
2794 successfully. Tested with two routers, two servers and two
2797 * Tested channel message sending in router environment successfully.
2799 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Added silc_server_save_channel_key into server.[ch] to save the
2802 received channel key in Channel Key payload processing. It is
2803 also used in JOIN command reply handling.
2805 Equivalent function silc_client_save_channel_key added into
2806 client.[ch] into client library.
2808 * Changed JOIN command reply to send information whether the channel
2809 was created or not (is existing already) and the channel key
2810 payload. Changed protocol specs accordingly.
2812 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2813 the request was sent by ID and not by nickname. Crashed on
2816 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2818 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2819 now correctly save the received data.
2821 * silc_server_free_sock_user_data now notifies routers in the
2822 network about entities leaving the network.
2824 At the same time implemented functions silc_server_remove_id
2825 and silc_server_send_remove_id to receive and send REMOVE_ID
2826 packets. The packet is used to notify routers in the network
2827 about leaving entities. The ID removed will become invalid in
2830 * Added function silc_idlist_del_server into server. Removes and
2831 free's server entry from ID list.
2833 * silc_server_private_message function now checks, if we are router,
2834 that the destination ID really is valid ID, naturally.
2836 * In router when NEW_ID packet is received (for new client) the
2837 hash of the Client ID is saved in the ID Cache but the
2838 client->nickname is set to NULL, instead of putting the hash
2841 IDENTIFY command now also checks that client->nickname must be
2842 valid. If it is not if will request the data from the server who
2843 owns the client. Added new function
2844 silc_server_command_identify_check.
2846 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2847 to set the command to already allocated Command Payload.
2849 * Tested private message sending in router environment with two
2850 routers, two servers and two clients. Fixed minor bugs and now
2853 * Fixed segfault from client's NAMES command. Used to crash if
2856 * Forwarded packets must not be routed even if it is not destined
2857 to the receiver. Changed server code comply with this.
2859 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * Added `require_reverse_mapping' boolean value to ServerParams
2862 structure. If TRUE (not default) the server will require that
2863 the connecting host has fully qualified domain name.
2865 If the reverse mapping is not required and hostname could not be
2866 found the IP address is used as hostname.
2868 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2870 * Implemented version string checking to both client and server.
2871 The check is incomplete currently due to the abnormal version
2872 strings used in development version of SILC.
2874 * Changed all command functions in server to use the new
2877 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Changed char *data to unsigned char *data in ID Cache system to
2880 support binary data as ID Cache data. Changed code to support
2881 binary data in lib/silccore/idcache.c.
2883 * Renamed silc_server_packet_relay_command_reply to
2884 silc_server_command_reply as it is normal packet receiving
2885 function. Rewrote the function to accept command replys for
2886 servers and not only for clients.
2888 * Mark remote router always as registered server if we are connecting
2889 to it. Otherwise, commands sent by the router to us are ignored.
2891 * All ID List find routines now returns the ID Cache Entry pointer
2892 as well if requested.
2894 * WHOIS command works now in router environment, tested with two
2895 routers, two servers and two clients.
2897 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2898 in router environment (as it is almost equivalent to WHOIS) but
2899 hasn't been tested thoroughly. Added new functions:
2901 silc_server_command_identify_parse
2902 silc_server_command_identify_send_reply
2903 silc_server_command_identify_from_client
2904 silc_server_command_identify_from_server
2906 * Disabled route cache adding because adding two different ID's with
2907 same IP replaces the old cache entry thus giving wrong route.
2908 The entry->router->connection is always the fastest route anyway
2909 so route cache may not be needed. Of course, new routes maybe
2910 established after receiving the ID when the entry->router->connection
2911 might not be anymore the most optimal.
2913 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Add route cache for received ID for fast routing.
2917 * Added silc_server_packet_route to route received packet on router
2918 that is not destined to us.
2920 * Renamed silc_server_get_route to silc_server_route_get.
2922 * Added id_string and id_string_len fields into SilcServer to
2923 include encoded ServerID for fast comparing without excess
2924 encoding of the ID's.
2926 * Cleaned up WHOIS command on server side. Added following static
2929 silc_server_command_whois_parse
2930 silc_server_command_whois_check
2931 silc_server_command_whois_send_reply
2932 silc_server_command_whois_from_client
2933 silc_server_command_whois_from_server
2935 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2936 arguments in command replies. All command functions should be
2937 updated to use this macro.
2939 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Minor typo fixes on command reply handling on server.
2943 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Added silc_server_command_add_to_channel internal routine to add
2946 the client to the channel after router has created the channel and
2947 sent command reply to the server.
2949 * Added generic silc_server_send_command to send any command from
2952 * Use static buffer with ID rendering instead of duplicating data.
2954 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2956 * Fixed a channel user mode bug when joining to a channel server gave
2957 everybody channel founder rights, oops.
2959 * We mark ourselves as the router of the incoming server connection
2960 if we are router ourselves. This way we can check in some packet
2961 sending functions whether it is locally connected server. For
2962 incoming router connections we put NULL.
2964 * For router sending packets locally means now always sending the
2965 packet cell wide; to local clients and local servers. For normal
2966 server sending packet locally means sending it to only local
2969 * Fixed the JOIN command to really work in router environment. If the
2970 channel is created it is always created by the router. Router is
2971 also responsible of making the initial joining to the channel,
2972 sending JOIN notify to the sending server and distributing
2973 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2974 does not exist server doesn't do anything else but forward the
2975 command to the router which performs everything.
2977 * Added silc_server_send_channel_key function to send the Channel Key
2980 * Added silc_server_create_channel_key to create new channel key. The
2981 channel key is now re-generated everytime someone joins or leaves
2982 a channel, as protocol dictates. Note: channel->key_len is the
2985 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2987 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2988 packet_receive.[ch] to separate packet sending and receiving
2989 routines. The server.[ch] now includes everything else including
2990 actual packet processing (writing and reading data) and other
2993 Renamed silc_server_private_message_send_internal to
2994 silc_server_send_private_message. The routine is still though
2995 used only to relay private messages as server does not send
2996 private messages itself.
2998 Renamed silc_server_new_channel to silc_server_create_new_channel
2999 and added new function sicl_server_new_channel that handles the
3000 incoming New Channel packet. Added also new sending function
3001 silc_server_send_new_channel to send New Channel Payload.
3003 * Added new function silc_server_notify to process incoming notify
3004 packet to the server/router. Server may then relay the notify
3005 to clients if needed.
3007 * Added new function silc_server_new_channel_user to process incoming
3008 New Channel User packet. Router will redistribute the packet and
3009 send JOIN notify to its local clients and locally connected servers
3010 if needed. Normal server will send JOIN notify to its local client
3011 on same channel when received this packet. Added also corresponding
3012 sending function silc_server_send_new_channel_user to sent the
3015 * Added boolean route argument to send_notif_to_channel and
3016 packet_send_to_channel functions to attempt to route the packet
3017 if it is TRUE and send only locally if it is FALSE.
3019 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3021 * silc_server_replace_id now broadcasts the received replace ID
3022 packet if it is not broadcast packet already. The router must
3023 broadcast to inform other routers about changed ID.
3025 * Added backpointer to server's router into SilcServer context in
3026 silcd/server_internal.h.
3028 * Fixed silc_server_packet_broadcast to send correct broadcast
3031 * The channel key is now distributed to the local client as soon
3032 as it is received from the router (in router environment) so that
3033 no other packet may be sent for the channel until client has
3036 * silc_server_remove_channel_user now broadcasts the received
3037 Remove Channel User packet if it is not broadcast packet already.
3038 The router must broadcast to inform other routers about removed
3041 * Added users field into SilcPacketContext that is a reference count
3042 of the context. One can increase the reference count by calling
3043 silc_packet_context_dup which is now changed to just increase the
3044 reference count instead of duplicating the data. The reference
3045 count is decresed by calling silc_packet_context_free that will
3046 free the data after the reference count hits zero.
3048 For now on the packet context and everything allocated into it
3049 (including the raw packet from network) must be freed by calling
3050 the new silc_packet_context_free function. Added also new function
3051 silc_packet_context_alloc that must be used now to allocate the
3052 context. This also means that if a routine is asynchronous from
3053 silc_[client/server]_packet_parse_type the packet context must
3054 be duplicated by calling silc_packet_context_dup. Otherwise it
3055 gets free'd after silc_[client/server]_packet_parse_type returns.
3056 Also, one must remember that if packet is duplicated then its
3057 reference count must be decresed by calling the free function as
3058 many times as it was duplicated.
3060 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3061 from both client and server.
3063 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3065 * Made joining to a channel working in router environment.
3067 * Cleaned up JOIN command on server side and create function
3068 silc_server_command_join_channel internal routine to make the
3071 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3073 * Changed silc_command_pending list to SilcDList. Also, added
3074 `ident' field to SilcServerCommandPending structure to identify
3075 the reply and to call correct callback.
3077 Added silc_server_command_pending_check function to replace the
3078 corresnponding macro. The silc_command_pending list is not
3081 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3082 to set identifier to previously allocated Command Payload. It
3083 is used to set identifier for command when resending Command
3086 * Added silc_command_payload_encode_payload to encode Command
3087 Payload buffer from SilcCommandPayload structure.
3089 * Added silc_argument_payload_encode_payload to encode Argument
3090 payload buffer from SilcArgumentPayload structure.
3092 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3094 * Changed WHOIS command to support router connection on server side.
3095 The whois request is always sent to router unless the server is
3096 standalone server. After server has received the reply from the
3097 router will it send the reply to the client.
3099 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3100 broadcast received broadcast packet. The function is used only
3101 by router. The broadcast packet is always sent to the router's
3104 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3105 render given ID to printable string, for log files for example.
3107 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3109 * Made basic router to router connections working. At least they
3110 can now connect to each other but nothing really works the way
3111 they are supposed - yet.
3113 * Added new initiator token to RouterConnection configuration
3114 file in silcd/serverconfig.[ch]. It is used to tell whether we
3115 are the initiator to the remote router or whether we'll expect
3116 the other end to connect.
3118 * Moved registering of listener task to silc_server_init, hence
3119 the server starts listenning as soon as it is run, even if it
3120 does not have connections to other routers. Let's see how well
3123 * Changed default connection retry timeouts for more suitable in
3126 * Removed cipher and such arguments from silc_idlist_add_client
3127 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3128 Added new function silc_idlist_add_data to add the keys and stuff
3131 * Added SilcIDListData structure and added it to SilcClientEntry
3132 and SilcServerEntry as their first field in the structure. This
3133 way we can explicitly cast the ID entries to the SilcIDListData
3134 structure and get common data for the entries. In past, we had
3135 to first check what type of connection it is and then cast it to
3136 correct ID entry type. Now, we can directly cast the opaque
3137 pointer to the SilcIDListData (no matter what ID entry it actually
3138 is) and get the data needed.
3140 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3143 in some circumstances even if threre were timeout tasks, though not
3144 IO tasks, but tasks anyway. Now fixed.
3146 * Defined SilcServerConnection structure to hold connection specific
3147 stuff about directly connected servers and routers. The definition
3148 is currently in silcd/server_internal.h. I thought about having
3149 a bit more important role fro this struct but for now it is used
3150 only when connecting to other server (or router actually).
3152 * Added connecting retry support in server when connecting to
3153 router(s). The retry feature implement exponential backoff
3154 algorithm. Also, added SilcServerParams structure to hold default
3155 parameters for server. For now, it include these retry settings
3156 and are hard coded. After server is moded to be as Silc Server
3157 Library this structure will be more important.
3159 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Changed client librarys channel->clients table to SilcList and
3162 changed code accordingly.
3164 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3166 * Changed client's channel table to SilcList and changed code
3167 accordingly. Also changed SilcChannelClientEntry to include back-
3168 pointer to the channel so that client entry can use that structure
3169 as list as well and we have fast cross-reference to the channel.
3170 This change dramatically decreased the complexity of channel
3171 handling with client entry and vice versa (removed one extra
3172 loop when searching for channel entry from many functions).
3174 * Changed server->sim from table to SilcDList and changed code
3177 * NAMES command can now be used from user interface. It will show
3178 the user list on the channel, neatly.
3180 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3181 Code now saves realname of the user if it becomes available.
3183 * Renamed configure.in to configure.in.pre and made ./prepare
3184 script to automatically add correct version string to
3185 configure.in which it creates from configure.in.pre.
3187 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3189 * NAMES command reply now shows users mode with the nickname when
3192 * Moved silc_client_ch[u]mode[_char] functions from
3193 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3194 place sucks, they are utility functions and should be in some
3197 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3199 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3202 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3206 * Added TRQ (efficient deque and list library) into lib/trq. This is
3207 a very good list library that is currently used in the SILC. Defined
3208 SilcList API over the library because I didn't like the API very
3209 much. See lib/trq/silclist.h for the API and examples of how to
3210 use the API. Fixed various places in the code to use the new
3211 SilcList API. The SilcList is meant for lists that has a structure
3212 already defined as a list. It is not suitable to add just some
3213 context to the list (in TRQ, the context is the list actually).
3215 So, I defined SilcDList that can be used for the purpose where
3216 predefined list structure does not exit. This can be used as
3217 such list. Now some context just can be added to the SilcDList.
3218 Currently this list is not used in the SILC just yet, though there
3219 are a lot places where this can replace dynamically allocated
3220 tables and I will fix these places, later, to use SilcDList.
3221 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3222 and use TRQ internally).
3224 Also fixed some annoying warning messages that the original TRQ
3225 code generated. Also minor changes to TRQ's Makefile.in.
3227 * Added support for querying by Client ID to both WHOIS and
3228 IDENTIFY commands into server, as required by the protocol.
3230 * Removed method function pointers from SilcBuffer structure. They
3231 weren't used to anything and just increased the context size for
3232 no good reason. This change also made silc_buffer_alloc and
3233 silc_buffer_free functions inline functions.
3235 * Disabled command flooding detection support until it's fixed so
3236 that it accepts commands in but does not execute them more than once
3239 * Added silc_net_localhost(), to return local hostname, into
3240 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3241 that must be initialized before calling silc_client_init.
3243 * Added new function: silc_server_send_notify_on_channels to send
3244 notify messages to all channels client has joined. It is assured
3245 that the message is sent only once per client.
3247 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3248 lib/silcutil/silcutil.[ch] as silc_format function. The new
3249 function is generic and is used by server as well, not only by
3250 the logging routines.
3252 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3253 the provided version string was not acceptable. Added new function:
3254 silc_ske_check_version into lib/silcske/silcske.h. The function
3255 must be implemented by the application (client or server) and it
3256 does not reside in the SKE library. The function checks the version
3257 string remote end sent.
3259 * Added back pointers (to opaque context and to SilcSocketConnection)
3260 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3262 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3263 duplicate packet context structure.
3265 * Changed `notify' client operation to send same arguments as client
3266 receives from server except for ID's. ID's are mapped to correct
3267 ID entry and that is returned. Also, if channel entry is not sent
3268 by server but the notify is for channel the channel entry is sent
3269 to application (otherwise application doesn't know that it is for
3270 channel (library gets it from packet's Destination ID)).
3272 * Added silc_client_remove_from_channels into client library to
3273 remove a client from all channels it has joined to. Used when
3274 received SIGNOFF notify from server. Added also new function
3275 silc_client_replace_from_channels to replace old ID entry with
3276 new ID entry on all channels. Used when received NICK_CHANGE
3279 * Fixed ID Cache list handling in silc_idlist_get_client in
3280 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3281 to get (or query) client by ID.
3283 * Updated TODO list.
3285 * Added connection authentication status message defined by the
3286 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3287 support for these into the code in client and server side.
3289 * Added generic function silc_client_send_command to send any command
3290 with variable argument list. Application should use this function
3291 to send commands if the command functions provided by the library
3292 does not suite for the application's user interface needs.
3294 * Added new `failure' client operation. Application is notified about
3295 received failure packet if client is executing a protocol. In this
3296 case the protocol's execution has failed.
3298 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3299 is required by the protocol.
3301 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3302 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3305 * Added status flag to SilcSKE object to indicate realtime status
3306 of the SKE protocol.
3308 * Application receives now exactly same command reply arguments as
3309 the library receives from server. However, if ID is received the
3310 corresponding ID entry is returned to the application (eg. Client
3311 ID is mapped to correct SilcClientEntry entry and that is returned).
3312 Changed command_reply client operation due to this change.
3314 * Changed all ID's in commands and in command replys as ID Payloads.
3315 Change affected both client and server side codes.
3317 All ID's sent in SILC network (with execption of ID's in SILC
3318 Packet header) are sent in ID Payload to support variable length
3321 * Server now notifies nick changes and notifies all clients on
3322 the channels about the new nickname (about the new Client ID,
3325 * Implemented CMODE command to change channel modes. Supports all
3326 channel modes defined by the protocol specs except ban and invite
3327 lists. (Also, private channel key mode is supported but support for
3328 setting private channel key in client is missing, thus, this mode
3329 has no effect on client side (except that server requires that the
3330 client uses private channel key and normal channel traffic does not
3333 Also, invite mode works per se, but INVITE command does not work
3334 yet correctly, so you can set channel as invite only channel but
3335 inviting clients to the channel does not work (it is yet to be
3336 thought what's the best way to do it).
3338 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3339 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3340 Implemented CUMODE command to change user's mode on the channel.
3341 Supports all modes defined by the protocol specs.
3343 * Added NAMES command reply to return users modes on the channel.
3345 * Removed unnecessary and slow ciphers from lib/silccrypt.
3347 * Set SO_KEEPALIVE option to connection sockets by default.
3349 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3351 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3352 redefined the Notify Payload into protocol specs.
3354 * Added silc_id_payload_parse_id to get ID directly from raw
3357 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3359 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3360 accept searching by Client ID as well.
3362 * Added support for LEAVE and SIGNOFF notify types in client library.
3364 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3365 to parse ID Payload from raw data.
3367 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3369 * Added flags parameter into silc_ske_assemble_security_properties
3370 function in lib/silcske/silcske.[ch].
3372 * Changed notify client operation to fit better for notify messages
3373 sent by server. The notify payload received from server is now
3374 passed to the application (after parsing it to SilcNotifyPayload).
3375 It is application's responsibility to retrieve the arguments
3376 from the payload and show the message the way it wants. The message
3377 sent by server is implementation specific.
3379 * Changed public keys to comply with the protocol specification.
3380 Old public keys are not supported anymore and are not compatible.
3382 * Removed nickname from Channel Payload as the latest draft removed
3383 it. The client must resolve the nickname from the NAMES command
3384 reply received when it joined the channel.
3386 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3388 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Fixed some errors in protocol specification drafts.
3392 * Created lib/silccore/silcnotify.c to implement Notify Payload
3393 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3394 generic payloads described by protocol specifications. The file
3395 includes implementations for ID Payload and Argument Payload.
3397 * Changed Command Payload implementation to use the new Argument
3398 Payload. Changed command_xxxx_payload to command_payload_xxxx
3399 to comply with SILC coding conventions.
3401 * Added suppport for Argument Payload handling in Notify Payload
3402 implementation as protocol requires it. Added the new support
3403 into server and client lib as well.
3405 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added support for multiple nicknames on same channel. [n] is
3408 added locally to the nickname if there are more than one same
3409 nicknames on the channel.
3411 * Server now sends all nicknames that matched WHOIS request.
3412 Client also shows the list received from server.
3414 * Added TOPIC command to client side. User can now set and show
3415 current topic on channel.
3417 * Added MOTD command to client and server. Also, server sends the
3418 motd when client connects to the server.
3420 * Changed version strings to comply ISO 8601.
3422 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Fixed protocol error handling in client library. It should now
3425 cope even if the SKE fails for some reason.
3427 * Made new protocol specification drafts for submitting to IETF.
3429 * Implemented TOPIC command to server in silcd/command.c.
3431 * Added two new notify types into lib/silccore/silcnotify.h:
3432 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3433 notify nickname change and topic setting/change on a channel.
3435 * API change of command_reply operation in client library. The
3436 application gets now the status type received from server as well.
3438 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3440 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3442 * Cras fixed and optimized the packet handling even further and
3443 it should work now. Minor change to the prototype of function
3444 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3446 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Added new function into lib/silcutil/silcschedule.[ch]:
3449 silc_schedule_with_fd to select() a specified fd. The function
3450 returns after timeout expires or data arrives or goes. The
3451 function is used by packet routines to wait that all data is
3452 received from network.
3454 * Fixed data reading from network in lib/silccore/silcpacket.c.
3455 The code now assures that all data is read from the fd and then
3456 continues packet processing. This was a bug fix since the code
3457 used to drop some data in some circumstances.
3459 * Added new function into lib/silcclient/client.[ch]:
3460 silc_client_start_key_exchange to start key exchange after
3461 connection has been established to server. The code internally
3462 now uses this funtion but its main purpose was to provide it
3463 for applications that perform their own connecting. After
3464 application has created a connection it merely calls this
3465 function to start the key exchange between client and server.
3466 The library takes care of everything else after that.
3468 Updated also lib/silcclient/README to explain the usage of
3471 * Do not send to application information that connection has
3472 been established. Application gets notified it by connect
3475 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Applied cras's patch to add silc_schedule_one function. The
3478 function runs scheduler once and returns.
3480 * Fixed the scheduler after cras messed it up. The timeout
3481 handling works now as it's supposed to work.
3483 * Added into lib/silccore/ silcnotify.h to include notify
3484 message types support. Changed silc_server_send_notify*
3485 functions, in server.[ch], to support those new notify types.
3486 Added the support for the notify types into client library,
3487 as well. Added new notify client operation into ops.h in
3490 * Changed silc_server_packet_send_to_channel to send normal
3491 packets instead of just channel message packets. The function
3492 is now used to send the notify packets to channels. It is not
3493 used to send channel message packets anymore, as server never
3496 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3497 va_arg()s as it seems to require it nowadays. I guess, if SILC
3498 is compiled with older va_arg() the new code should work anyway.
3500 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3502 * Splitted core library. Core library (lib/silccore) includes
3503 now only SILC protocol specific core (and common) components.
3504 Created new utility library (lib/silcutil) that includes more
3505 generic purpose stuff. The stuff for util library was taken
3506 from the old core library. This was minor and easy split.
3508 * Created SILC Client Library (lib/silcclient) that includes
3509 implementation of the SILC client without user interface. This
3510 was major move from silc/ directory. The code has been changed
3511 so that it is transparent towards the user interface. The
3512 silc/ directory includes now the same user interface as before
3513 and it uses the new client library. Read lib/silcclient/README.
3514 Basicly, the client library performs everything else related
3515 to SILC except user interface handling. Also, configuration
3516 files are considered to be part of user interface and library
3517 does not handle them.
3519 This change also changed a lot of structures, function naming etc.
3520 Most important change was that SilcClientWindow object was
3521 renamed to SilcClientConnection in the client library. Created
3522 also new file lib/silcclient/ops.h. Also added new files
3523 silc/local_command.[ch] and silc/client_ops.[ch].
3525 All these changes were made to make it easier for user interface
3526 designers to create what ever user interface for the SILC client
3529 It is also expected that the server will be moved to lib
3530 directory as well and SILC Server Library will be created;
3531 sometimes in the future.
3533 * Removed Local commands from lib/silccore/silccommand.h as
3534 they are application specific and new client library does not
3535 handle any of those anymore.
3537 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3538 old client implementation in silc/.
3540 * Added support for callback functions in SILC_LOG_* macros.
3541 Application can now set its own callbacks that will be called
3542 instead of using the default functions that will always print
3543 the debug messages to stderr (or stdout). Also, debugging can
3544 now be disabled by setting silc_debug to FALSE and re-enabled by
3545 setting it to TRUE. Note, that logging will still work even
3546 if debugging is disabled.
3548 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3549 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3550 silc_log_reset_debug_callbacks.
3552 * To enable debugging in silc client one must give now -d
3553 option on command line.
3555 * Changed silc_schedule_init to automatically allocate task queues
3556 if they are not allocated before calling it.
3558 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3560 * Added GMP 3.1 into math library.
3562 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3564 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3565 a channel in SILC network. The packet is used by servers and
3566 routers to notify other routers that user has left a channel.
3567 This little feature was missing until now. Added the feature
3568 to protocol specification as well.
3570 Added functions: silc_server_send_remove_channel_user and
3571 silc_server_remove_channel_user into server.[ch].
3573 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3574 lib/silccore/silcpacket.h. However, they are not implemented
3577 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3579 * Fixed joining to a channel and sending channel messages
3580 between server and router. The channel message sending should
3581 now work inside a cell.
3583 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Fixed the private message sending between server and router.
3586 The private message sending should now work inside a cell.
3588 * Added silc_server_replace_id into server.[ch] to replace
3589 existing ID in the SILC network.
3591 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3592 and silc_idlist_replace_server_id into idlist.[ch] in server.
3594 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3596 * Fixed the server to server connections. Server can again now
3597 connect to router. Router to router connections probably does
3600 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3602 * Added dynamic protocol registering support. Now protocols can
3603 registered and unregistered on the fly. Patch by cras.
3605 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3607 * Added lib/contrib directory to hold routines that some platforms
3608 don't have but are needed by SILC.
3610 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3611 into lin/contrib to provide getopt() and getopt_long() for
3612 those who don't have it.
3614 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3616 * Added AWAY command to client. When away message is set and
3617 client receives a private message packet the client automatically
3618 replies to the sender with the away message.
3620 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3621 bug seemed to be the cause of recent problems when compiling
3624 * Added version detection support to SKE protocol specification
3625 and added the new changes to the SKE implementation as well.
3626 There were other minor changes in the SKE protocol as well.
3628 Many changes in lib/silcske/silcske.[ch] and in
3629 lib/silcske/payload.[ch].
3631 * Added ^U functionality, clear input line. Patch from cras.
3633 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Mainly small bugfixes on core library. Fixed some debugging
3636 logging and buffer overflow in silclog.c.
3638 * Updated config.sub and config.guess on the distribution tree.
3640 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Added command lagging support in server. Client may execute
3643 commands now only once in two seconds.
3645 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3647 * Optimized packet reception. MAC computation and checking is now
3648 also more optimized. A lot previously duplicated code is now
3649 used as generic by both client and server.
3651 * Fixed key pair generation in clientutil.c
3653 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Added into lib/silccore/silcbufutil.[ch] new function;
3656 silc_buffer_realloc.
3658 * Moved generic packet sending/encryption functions to
3659 lib/silccore/silcpacket.[ch] from client and server. Some
3660 rewriting of the functions.
3662 * Moved all generic packet reception/decryption functions to
3663 lib/silccore/silcpacket.[ch] from client and server. The
3664 packet processing is now much cleaner in both client and server.
3665 These were major changes in both client and server.
3667 * Created many common functions in server to do packet sending.
3668 Previously code were duplicated a lot, this has been removed
3671 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3673 * Rewrote major parts of the ID cache system. Don't know
3674 whether it is better now or not but at least the API is more
3677 * Major rewrite on ID cache stuff on client because of the ID
3678 cache API changes. Added idlist.c to client.
3680 * Also major rewrite on ID cache stuff on server as well.
3681 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3682 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3683 in hand, instead they are all put into the ID cache system now.
3684 All server_idlist_* routines uses ID cache now instead of
3685 traversing its own lists (those lists does not exist anymore).
3686 SilcIDList though still exists. Also, SilcXXXEntry's are
3689 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Finally made the SKE implementation compliant to the protocol
3692 specification. All mp integers are now binary encoded as
3693 opposed being HEX encoded.
3695 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3698 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3699 functions: silc_[encode/decode]_pem. Also added function
3700 silc_encode_pem_file to PEM encode with newlines ('\n') for
3703 * SILC public keys are now encoded either PEM or binary. Same
3704 option is for private keys as well. By default private keys
3705 are binary encoded and public keys PEM encoded. Silly HEX
3706 encoding were removed.
3708 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3709 function to create fingerprints.
3711 * Fixed a bug in SHA1; does not change the original data anymore.
3713 * Partly implemented INFO command on client and server side.
3714 Fixed CLEAR command. Changes to SERVER command; show current
3715 server(s) when giving command without arguments. Added
3716 VERSION command to client.
3718 * Added check to server that unregistered connections cannot
3719 execute commands (unless it is specificly allowed).
3721 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Fixed screen refresh.
3725 * Fixed channel joining bug from client. On some circumstances
3726 client tried to join to a channel it had already joined.
3728 * Added public key verification process into client's protocol.c.
3729 The client now verifies the public key from user and saves
3730 it into ~./silc/serverkeys/ directory.
3732 Added into: clientutil.[ch]: silc_client_verify_server_key.
3734 * Changed SKE protocol's silc_ske_initiator_finish function
3735 to accept callback function that verifies the received public
3736 key. Removed old silc_ske_verify_public_key function.
3738 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3741 silc_pkcs_private_key[_data]_set.
3743 * Made the password and public authentication more cleaner in
3744 server's protocol.c.
3746 * Removed historic and obsolete protocol `channel_auth' from
3747 both client and server.
3749 * Removed wrong way of sending command status messages from
3750 server to client in server's command.c. The old way violated
3751 protocol specification.
3753 Changes to silccore/silccommand.[ch]: removed
3754 silc_command_encode_status_payload -> not needed anymore,
3755 changed silc_command_encode_payload_va to accept extra
3756 argument on variable argument list. The argument type must
3757 now be provided to the function. Also, added new function:
3758 silc_command_encode_reply_payload_va which is same as
3759 normal command_encode_payload_va except command status type
3760 is provided as extra argument.
3762 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Added ~./silc directory handling. The directory includes the
3765 public and private keys for the client.
3767 Added silc_client_check_silc_dir, silc_client_create_identifier
3768 and silc_client_load_keys.
3770 * Implemented SILC protocol compliant public key. Added public
3771 and private key saving to and loading from files.
3773 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3774 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3775 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3776 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3777 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3779 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3780 silc_pkcs_load_[public/private]_key.
3782 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3784 * Added silc_server_get_route (route.[ch]) to get connection
3785 data for the fastest route for given ID.
3787 * Implemented INVITE command on client and server. The command
3788 were re-defined in the SILC Protocol Specification and the
3789 implementation now complies with the specification.
3791 * Implemented PING command on client and server.
3793 * Implemented NAMES command on client and server. The server side
3794 supports currently only normal server not router server yet.
3795 Some changes to NAMES definition in SILC protocol specification.
3797 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3799 * Implemented LEAVE command on client and server.
3801 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3802 again. This change was made to the protocol as well. Server
3803 should not violate the protocol specification anymore.
3805 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3807 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3808 was tested. SOCKS4 was not but should work anyway.
